A separate jump list for vim-like tag navigation

[igoralmeida]

Hi, thanks for better-jumper!

It seems doom emacs uses better-jumper instead of some evil jumping functions, so here's a [long] question. As a vim user, I am missing the separate "tag stack" functionality when using emacs, and I was wondering if better-jumper could work for that.

Basically, the jump list is polluted by several commands (for example, evil-window-top, evil-forward-section-begin, evil-scroll-down...) that are inconsequential to code navigation, and it would be nice to jump backward and forward only to places where there are definitions of functions, for example. Those intermediate jumps -- in, for example, the current file -- can be distracting when trying to go back to the last function definition. Of course, there are cases where they are valuable.

I took a look at better-jumper.el and wondered if there could be a better-jumper-set-definition-jump (like better-jumper-set-jump) the uses a separate jump list struct. This would probably need to be similar to the 'window context since you'd be navigating to different files with something like evil-goto-definition.
I don't fully understand the code, but it seems that the calls to better-jumper--get-struct and better-jumper--push could have some more args to be able to differentiate between this "better-jumper-set-definition-jump" proposal and better-jumper-set-jump, to make sure the correct jump list is used.

Thoughts?
