I use a lot of tabs in my Vim workflow, and each tab may have several splits in them. I recently discovered in Preserving equal sized split view that having this line in my vimrc helps will automatically make my splits equally sized.
autocmd VimResized * wincmd =
However, it only seems to resize the current tab I'm on if I resize the window that Vim is in. For other tabs, the splits are still unequally sized. Is there a way to automatically resize the splits in all tabs when the window size changes?
