Feature Idea: Slider Mode

[nyngwang]

Let's review what NeoZoom.lua does first :D

The main focus of NeoZoom.lua is to help you focus one window at a time. This is done by turning two of the drawbacks of float window into an advantage: floating window makes you feel temporary, and it covers other windows in your current tabpage. (blablabla, lol)

Problem(?)

To make NeoZoom.lua works for a window, you still need to move your cursor to the window first. This wastes some seconds for me and I don't like it.

Ideas

So the current workflow looks like this:

I'm in a tabapge --> I need to focus on a window --> I move my cursor toward it --> I run keybind/command from NeoZoom.lua --> repeat if I I need to switch focus

What in my mind currently:

I'm in a tabpage --> I run keybind/command from NeoZoom.lua --> I can cycle-through all buffers in the current tabpage --> Yeah

I give this workflow a name called slider mode because why not, lol.

Pros & Cons

Good:

• NeoZoom.lua is now also window selector, and it's cool.
• Or maybe It's not just cool, if you really think about it:
  • Under Vim's philosophy, we can always re-open another buffer from any existing tabpage.
    • In other words, Vim's saying "hey, the point of tabpage for you is that you can store many window layouts".
    • But I don't use tabpages for just window layouts. I use tabpages for subtasks under the current project(and there are plugins to set a title for each tabpage).
    • That is, I use tabpages to remember what buffers are needed for each subtask. But creating many windows under a given tabpage makes me hard to focus.
  • If NeoZoom.lua becomes a window selector, I can keep both "subtasks" and "focus" ideas!
    • I don't even need to maintain any state to remember all the buffers for a given tabpage, because the upstream API nvim_win_get_buf() has done it! This is a good sign to add this feature because no state management is involved.

Bad

• I haven't thought about it too much, but the implementation probably involves some tricky edge cases when we "sliding through" each buffer under the current tabpage, since NeoZoom.lua currently provides executing callbacks on zoom. (and I haven't implement The option opts.callbacks should be further splitted into two cases: zoom-in & zoom-out #93)
• More user commands
• NeoZoom.lua will do two things rather than one.

End Result Sketch

• So I probably need a pair-window to list all buffers under the current tabpage, as shown in my sketch.
• In BUF_LIST, hint users their keybinds to "slide through" every buffer. (They don't need to read my repo to know WTF has been added :D)
