AutoHide Tab Bar + Address Bar | Show on Hover

kostasvl

@oudstand For me, the address bar is shown at all times, with your unmodified version. For example:

I can repro this with your version from January as well, although that wasn't the case initially, back in February. Something changed in Vivaldi since. It's strange that it doesn't repro for you. There is at least one more report in this thread: https://forum.vivaldi.net/post/805076.

Worth noting that I have no other mods at all. Just your ace one

It's not a problem though. My tweak accomplishes the same thing (see screenshot in my previous reply).

Thanks

@masklessdiety I'm preparing a forum post where I'll offer a script that automates the update process entirely. It starts when you boot into Windows (via the Task Scheduler), and then monitors the Vivaldi directory for those versioned subdirectories. When it detects a new/higher version, it prompts you to close Vivaldi, and then it copies your mods from a directory of your choice (together with your modified window.html) into the Vivaldi directory. Then it asks you to restart Vivaldi, and goes back to monitoring for new changes.

This literally happened 20 mins ago

I just need time to prepare the post, with instructions, screenshots, etc .

Hmm, would you (or anyone else here) like to beta test it for me? I have two alternatives:

An exe:

This exe will not show a window at all, which is important.

The thing is, I'll offer the exe (via Google Drive, probably), but, no one should be downloading executable files from strangers... I can offer the source code too, if you have the means to compile it. Visual Studio Community Edition, or VSCode, are both free. That might be too much to ask of people, so I also prepared...

A version of the same thing, written in powershell.

Less dangerous in theory, because people can see what it's doing. The problem is that it will show an annoying window when you run it. Solving that is a bit annoying, though doable.

Anyway, I'll stop here for now. If there is interest, I'll write back. At the weekend, I might track down that big forum post where people discuss their own scripts for this, and I'll post my stuff there.

Really though, I wish Vivaldi will implement a solution

I'm okay with trying both versions, though not sure how much I can help, I only know how to copy and paste things into directories, zero programming knowledge

For me, the address bar is shown at all times, with your unmodified version.

@kostasvl I didn't tested the old code again. Does it still happen with the latest code that I've provided? I also implemented the .UrlBar-AddressField:focus-within) fix there.

@kostasvl I prefer to patch Vivaldi with a batch script when needed

Since I use Vivaldi on different devices my script even pulls my latest mod changes from git.

kostasvl

@oudstand Yes, that IMDB screenshot was taken with your latest version.

@kostasvl I can't reproduce it with the latest code. Do you have any other mods enabled which could cause the problem? Just to be clear, this ist my latest version:

@oudstand No other mods.

oudstand

@kostasvl hm... that makes it difficult to fix for me when I can't reproduce the problem...

kostasvl

@oudstand No worries, thanks!

Firipu

I am using your mod. It works wonderfully, but the panels don't show anymore (I changed hide panels to false in the JS script) . I just get a little grey bar with an arrow. But panels are invisible. If I toggle them, the little arrow goes from the left to the right and that's it.

I use vertical tabs.

The little grey bar with black arrow in the top right is all that shows for panels.

Am I doing something wrong? I am using the last version of the code on this topic.

oudstand

@Firipu I've tested it with the latest code and it does work. Do you have any other JS or CSS mods that could affect this mod? Did you try to restart your browser?

Firipu

@Firipu

Ok, so just for reference, if anyone else would have the same issue:

Turning on floating panels in your settings solves the issue. The panel bar stays nice and visible now.

edit: restart fixed the transparent tab bar.

script works flawless now. Thx! Leaving this up for future reference if anyone else would have the issue.

oudstand

@Firipu good to know. I've always used floating panels. On my device the color of the side bar didn't disappear, but as long as you're happy with it

No9527

@oudstand This code runs perfectly on my PC. Will it work on Mac OS X (M-chip) too?

oudstand

@No9527 I only have tested it on Windows, because I don't have a Mac. So give it a try and let us know

Sullie

@oudstand, thanks for the code and your effort. Works nicely for the most part. However, I am seeing a glitch with the Workspaces button on the vertical tabs panel--it kind of blinks rapidly to the extent that I cannot interact with it. Could you also please make a version which auto-hides the status bar?

oudstand

@Sullie currently I don't get the workspaces button fixed, I don't know exactly why this happens. As soon as .tabbar-wrapper gets position: fixed; it's not working anymore. Maybe I'll find a solution in the future.

For the moment I could fix the status bar and also the transition of vertical tabs looks nicer.

@shenghuoyishujia What if we have the tab bar elsewhere? Like in my case on the bottom?

This AutoHide is very irritating to me. Why is there a checkbox in the panels tool selection that can't be simply un-checked. I feel I'm constantly being outsmarted in a bad way in the update department these days, take Google Search. I was very happy with my panel always active and displaying bookmarks, I have thousands. Give me a checkbox for that. I'll be on Win10 Enterprise for the foreseeable future.
