[Enhancement] vi styled jump

[nisargsuthar]

I really like the jumping mechanism inspired from vim.

It can further be optimized as a small QoL improvement:

• Allow jumping by using vim like expressions such as 5k or 3j or whatever the Up and Down are mapped to. It gets rid of having to type signed numbers resulting in fewer keystrokes.
• Have the option to always have the relative numbers visible so that it updates with the selected item always being 0.

Thats cool but how would you then switch between tabs? This will need discussion before breaking someones established workflow. Maybe we could do [+|-]n[j|k] but thats again taking established keymaps (that have alternatives) and not really vim motion + redundant. Or maybe Jn[j|k] (3 keys) would be better than J[+|-]nRET (4 keys) I'm personaly not keen on mod+n to switch tab.

How about we extend the existing swap mechanism between the first 2 tabs? We can put a delay distinction to identify either (Tab) or 2x(Tab), let's say 0.5ms apart.
And then a simple workflow can be:

• (Tab)(Tab) = Create 2
• (Tab)(Tab) = Create 3
• (Tab) = Switch to 1
• (Tab) = Switch to 2
• (Tab)(Tab) = Create 4

So any time 2x(Tab) is recorded, create a new tab otherwise cycle forward. Additionally, (Shift)(Tab) to cycle in reverse direction.
