-- Initialize folds with foldmethod = expr if a treesitter parser is available, then switch back to manual
-- This is to have the folds calculated and closed when editing the file initially, but with foldmethod set to manual
-- Without foldmethod set to manual folds are created while writing in insert mode which is annoying
--
-- Skip floating windows, because they often are documentation (and thus should be visible by default)
