DidYouMean Vim plugin is very simple: it asks you if the file you are trying to open is indeed the right file. How is this useful? Here’s how:

Say you have two files with a similarly starting names: model.py and model_test.py . You type vim mo , you hit tab to autocomplete the name, you hit enter. In vanilla Vim, you’d be opening a new file: model , since that’s where shell’s tab-completion stopped. DidYouMean detects such a nuance and asks you if you wanted to open model , model.py , or model_test.py .

Simple idea, and instantly after trying this out, I would really expect this feature to be included in vanilla Vim.
