This feels like a highly personalized customization to me. But if we get a ton of "HECK YES WE WANT THIS MERGE IT PLEASE!" I'll be delighted to do so.

@feoh I added those keymaps because similar ones that allow changing window focus without using <C-w> are included in kickstart.nvim. It seems odd to me that window movement still requires <C-w> but window focus doesn't:

kickstart.nvim/init.lua

Lines 186 to 190 in 34e7d29

	-- See `:help wincmd` for a list of all window commands
	vim.keymap.set('n', '<C-h>', '<C-w><C-h>', { desc = 'Move focus to the left window' })
	vim.keymap.set('n', '<C-l>', '<C-w><C-l>', { desc = 'Move focus to the right window' })
	vim.keymap.set('n', '<C-j>', '<C-w><C-j>', { desc = 'Move focus to the lower window' })
	vim.keymap.set('n', '<C-k>', '<C-w><C-k>', { desc = 'Move focus to the upper window' })

Feel free to close the PR if it's not desired of course.

Hey thanks for the explanation. I like the idea!

Anyone have any feelings about this? I'd just love a second "I want this" before I merge.

I liked it, it was more simplified.

I won't use these, but I like the idea of including these as a helping aid guiding people to learn about windows and tabs and stuff

Thanks everyone for chiming in! Merging!
