Feature: Fill gaps when creating new terminal

[edlandm]

This is arguably a preference that could be a setting, rather than the way things always should be, but if I open three terminals (Term_0, Term_1, Term_2) and then I close Term_1, I would like the next terminal created to be a new Term_1 instead of Term_3. This allows the jump_tab_mappings to have greater value because you're less likely to have terminals with double-digit indexes. I compulsively close my terminals when I'm done with them, so it's not uncommon for me to spin up over 10 terminals within a session.

Thanks for this project by the way, I think that it's very promising.

It's not a problem I have, since I only use two terminals personally. I know how to solve it, but I can't promise that this feature will be fast. I'm currently writing my graduate thesis. But if you send a PR, I'll gladly integrate it.

Copy that. I'll make a PR when/if I get the time, otherwise no worries. Definitely focus on your thesis 😄
