I've never liked nerdtree, everybody seems to suggest it but I never saw any utility in what it does. Why would I want a filebrowser taking up an entire window in vim when I have wildmenu command line completion for :e and, for deeper directory trees, fzf (although I only started using that recently, nerdtree never made sense to be before then either)? I do wonder what your gripe with the autocomplete dropdown is though, vim's built in TUI completion dropdown (this isn't something plugins invented, it's in Vim by default) seems to work just fine for me. The only completion plugin I use is supertab, which I understand to be dated and out of vogue these days, but it gives me continuity with command line completion being triggered by my tab key. The dropdown works exactly like I'd expect it to; tab and shift-tab to cycle up and down, and enter to select a completion. If I continue typing with it open, it refines the suggestions on the fly. I'm not sure what else I should ask for.
