-- TODO: Markdown preview does not work yet (It does work on a fresh linux installation)
-- TODO: When having initialized a new git repo in a folder in which the main latex document lies, the GIT.gitignore does not yet get generated, as per the eekhof-latex-package, when compiled with vimtex
-- TODO: A weird bug with nvim-cmp occured after typing a linebreak, which displayed some red error message in the console, inserted the last completion that was made at that wrong spot, and crashed the completion so that no other completions were suggested in that buffer, until it was restarted
-- TODO: Jumping from PDF in Zathura to latex source code with ctrl+click does not yet work, for start of solution see maybe https://www.ejmastnak.com/tutorials/vim-latex/pdf-reader/

-- -------------------------- gallium recommendations
-- In qute, "a" and "e" are not bound, making remapping to gallium very easy, since "h" just stays where it is (shifted one to right from querty). So I just have to remap the movements, and their capitals, and i for inserting into field to k (see below)
