Zoom, Find in Page & other actions in Web Panels

random94

Hello, is it possible to make all pages load at the default the zoom value? Currently, I have set the DEFAULT_ZOOM to 0.7. When opening panels for the first time, reloading the page, navigating within the panel, etc causes the zoom level to reset to 100%.

LonM

@random94 I never managed to figure out how to make that work. It might not be possible. If someone else solves it, I can add it in.

@random94 The Web Panel zoom is always set to 100% and is not changeable.

Vote for Change Web Panels Zoom

To have web pages remember their zom level, in Settings, Webpages, disable:

Use Tab Zoom

This will record the zoom level for each site where you change the default zoom from 0.7 to something else, so is a privacy risk.

chrome://settings/content/zoomLevels (fixed broken link)

@pesala said in Zoom, Find in Page & other actions in Web Panels:

vivaldi://settings/content/zoomLevels

I have this view on vivaldi://settings/content/zoomLevels :

Where I can find "default zoom from 0.7 " ?

@mikhailkap
Hi, simply search for zoom in the settings search field, you will get UI zoom and the page zoom settings. There you can change the Use tab Zoom setting.

Cheers, mib

I allowed CSS mods in vivaldi://experiments, added the file to a folder and selected it in "custom UI modifications". Nothing happened, even after restarting the entire OS. Am I doing something wrong?

@ladeira42
Hi, if you meant the code @LonM posted, this is a java script file. These does not work with the experimental settings.
You have to edit the browser.html in the Vivaldi application folder.
Windows/Users/user/Downloads/Vivaldi/Application/5.5.2805.42/resources/vivaldi
This is a Linux path, you can find the executable path in the Help > About menu.
Save the code as filename.js and copy it to the same folder.
If you open the browser.html with a text editor you can see how the other .js files are implemented in the file.

<script src="yourfile.js"></script>

Cheers, mib

@mib2berlin It worked! Cheers!

At newer vivaldi 5.7 maybe need some updates
Some icons gone and the panel bar becomes too thick
(Maybe some browser's code changed causes...)

Hopes the new update
(The function still working... but need to guess where the button is XD)

LonM

@YsPan I've updated the code now to work with 5.7. Thanks for reporting the bug detective

YsPan

@LonM It seems fixed, thanks you very much!

ladeira42

@LonM is it possible to force dark mode from start in this script? Sorry to bother. :s

LonM

@ladeira42 I have had difficulty in the past making the mod work with auto loading certain features when the site in the panel loads, so I don't think that is possible.

ladeira42

@LonM Well, it was worth trying. Haha
Cheers again!

Considering Vivaldi already has some these functions, the most important one that remains is the find in page on webpanels, does anyone has implemented the code for using the top of buttons?

joao.rossa

I was trying to put the search text button in the top bar, and i've got it working but there's some instances that it wont show when you close/hide the panel:

                upgradePanel(alreadyOpenPanel);
            }
        } else { setTimeout(initMod, 500); }
    }

    /* Start 500ms after the browser is opened */
    setTimeout(initMod, 500);
})();

joao.rossa

Don't know why they didnt add this functionality when they add the zoom button ones, also where's the default zoom button? they forgot?

Is it possible to use this mod to inject a script into the page? (Eg, a css stylesheet?)
