Add the ability to pin web panel tabs to sidebar

[D4rkMn]

im new to zen and so far i really like this browser! one feature i really like is the zen sidebar:

but i think it would be a really cool addition to be able to "pin" tabs onto the regular sidebar for more quick access.

for example, say im browsing yt on the zen sidebar, and then i close the sidebar for the moment being. well, then if i want to open it again, i have to click on the zen sidebar, then click on yt, which is two clicks. also, if i want to switch to another sidebar tab, well, open zen sidebar, switch from my current tab to another, and such.

i know it sounds kinda stupid but it really adds over time, especially for a feature that is supposed to allow for quick access to tabs, so it would be really cool if something like this could be added.

im envisioning something like opera's sidebar, where one can have multiple icons, each corresponding to a separate dedicated sidebar panel for each:

and the idea would be that you can pin as many as you want, so you can have your own custom quick sidebar tabs. it would be a very nice qol feature imo
