Trying out the extension and it's pretty good. Wondering if it would be possible to add an option to add url of the tab underneath each tab title (right now it is either tab title or url, it would be useful to have both),
because some websites don’t tell you anything on their title,
while some websites don’t tell you much from the url,
especially when I have a bunch of different pages open from the same website, it takes a while to find the tab I am looking for.
Thank you so much for the extension.

Edited: OMG that was so fast. It was impossible to find an actively developing sidebar/vertical tabs extension with this function. Thank you so much!
