Request: Adding twisties to each tree level

[silverwings15]

Hi Pika. i just made the jump from TST, and while not a huge fan at first, i found it proving to be a very capable replacement after some tweaking. i just have one feature request, that we have an option to add twisties/splitters to each tree level as TST does. right now it only adds twisties to the top level tabs, and not the secondary level tabs

thanks for your work on this extension

edit: some more small requests that probably don't warrant their own threads. let me know if you want me to make specific threads for any of them

• an option to make the twisties/splitters always visible
• an option to remove the underline text indicating a tree with children is collapsed
• an option to remove the glow on hovered tab
• a counter to indicate the number of tabs in a tree when there is more than 1
