Feature Request Make all tabs available to be manually inserted in the "Add Tab" context menu

Hello, it would help a lot to have all tabs available to be manually inserted via the context menu, some already are, but not all of them. (Pic.1)


(Pic.1) - Some options are already there, no reason for such a limitation.
This would be an excellent feature because:
1) It would be possible to insert the desired tab faster and without the need of the precise movements required to dock the window.
2) Docking relies on the user's Windowing System and Window Manager, which may introduce incompatibilities, like on my case, docking doesn't work at all.
2) It's already there, just replace the "Add Tab" with the Window tab and attach automatically.
