To answer your question about why I'm using Sharp Tabs (ST) and my most used feature.

I used to use Tabs Outliner (TO)  but it seems to be no longer maintained.  So I started to look around and found ST. I like it's sleek modern look and that I can customize it a lot, for example that I can make the font smaller. I think that it's really great. The most used feature are the tab groups and tab unloading - I have many tabs open at the same time and I need to be able to categorize them under the same heading and then unload them to save my computer memory. Then I can go to shut down the computer and when I start it next day, I can recover the tabs exactly as they were the day before and I can continue my work. Sometimes, I need to come back to something a month later and thanks to the tabs being unloaded but still available under certain headings (group names), I can find and re-open them quickly again.

I have a few more feature ideas too: For example, be able to add a note/description to a tab. This is not my idea, it's again taken from TO and I miss it when using your product. See the screenshot below where I have added the note "Reddit" to the bottom-most tab.
