Tab Rename

One problem. When the address bar is white that is when the address bar has a white background, the pen symbol does not show at all because the pen symbol you use is white (as I assume you use a dark background that has a black address bar so you need a white pen to see it). You seem to have done your pen in the address bar only when the address bar has a black background. BUT you forgot to do it for when the address bar has a white background and, in such a case, the pen should show only if the pen is black in this second case; in my case, it only shows a full white space on my address bar instead of a space showing a black pen, as it shows a white space and your white pen but because your pen is white, it ends up showing only a white space. Moreover, it would be better to allow an icon of your addon to be pinned to the toolbar instead of using a full space on the address bar for every single tab, as I have to change the name of the tab extremely rarely. Especially considering the fact that your space on my address bar (that has a white background) shows only as a white space without displaying at all a black pen because you created only a white pen for your address bar that has a black background. Thanks to correct this issue if you can. And thanks to the developer for this addon.

Nice, but when using Windows scale (125%), the icon is not visible.

Works ok but extremely annoying that it doesn't automatically select the existing text. You have to manually select and drag multiple times to get to the end of long existing text.
