tabs in panels?
is it possible to have tabs inside panels like in lazygit ?

Currently not without writing your own functionality that does this. If you want to do that, you can check out https://github.com/rivo/tview/wiki/Primitives.
If you look at the presentation demo code, there's something similar in there, with a TextView for the "tabs" and a Pages primitive for the content. The code is here. It's conceivabe to wrap this functionality in its own class so you can have multiple such elements on a page.
Let me know if this helps.
TabbedPanels is an example of extracting this functionality to a new class. Let me know if you'd like a PR.
