Replace Toggle buttons with switches

changed the description

I agree that the current state should be communicated better, but i don't think switches with labels could fit into the toolbar. We could put them into some sort of overflow menu.

Alternatively, we could keep the toggle buttons but give them a distinct active style to show the state. I would also suggest using icons instead of text to save space and avoid potentially confusing wording. I've made a quick mockup:

toolbar-mockup

Unfortunately, that would be a bit annoying to implement because the API for v-btn-toggle is weird.

The way it looks in my screenshot above, a switch should be possible. A problem with toggle buttons is that they don't communicate their state as clearly: Even with a distinct active style you are still missing a passive style. I guess one could give them colors like red and green/blue but that still doesn't really say "hey. you can toggle me".

Another possibility could be

checkboxes

The way it looks in my screenshot above, a switch should be possible.

Iirc you have a relatively large screen. On my screen it looks like this:

And that's without the switches. 1366x768 is still a very common screen resolution (source: https://gs.statcounter.com/screen-resolution-stats/desktop/germany).

That's true, but i think they are still a good compromise to save space. The concept of toggle buttons is fairly well known. Most of our users have probably used Microsoft Word at some point:
