Instead of opening a new thread I figured just adding to this one might be good.
After being able to place all sorts of normal buttons on the panel toolbar, it is also possible (for a while now) to place custom buttons on the toolbar. This means that you can use your panel bar as a bookmarks bar in unison.
I have changed my Vivaldi Forum and Vivaldi Social web panels into custom buttons, meaning that all other favicons on the panel bar are actual web panels, while the Vivaldi and Mastodon logos open the respective web pages in a new tab. Previously I had the corresponding pages set up as web panels, and middle clicked the icons to open them as a (background) tab instead of opening the panel. But this is much more convenient now.
Steps (there might be an easier way, this is how I did this):
get a 16x16 pixel favicon of the page you want to add, for example hit ctrl+u on the web page to view the page source, and look for the favicon links there, usually far up at the top.
in the powerful image maniupulation program Microsoft Paint, create an empty canvas size 28x28 pixels. Copy & paste the 16x16 favion into this canvas and center it. Then, using the bucket tool, make all the canvas around the favicon black, this will become a transparent color in step 3. Save as a png.
Since I have no clue how to save png files in Paint with a transparent color, I then used IrfanView (hello
@Pesala 🙂 ) to open the picture, and save it again as png, making sure to have "save with transparent background" selected. This allowed me to make the previously black areas from step 2 transparent.
In Vivaldi, create a command chain with the single action "Open in New Tab" which opens the web page of your choice. For example, I now have a "Vivaldi Forum" Command chain with the Action "Open in New Tab" and the target "
https://forum.vivaldi.net/unread"
In the themes editor, go to icons, scroll the list all the way down to find your new command chain, and give this command chain the favicon png that you saved in step 3. This is your new custom button
customize the panel toolbar, find your new custom button in the Command Chains section, and drag that to the panel toolbar.
Voilá: two bookmarks instead of panels on my panel toolbar, along with separators and status bar icons.
