Here are two I would absolutely love .
Importance : Major
- Icons in the tab bar.
- A stylish autocomplete (changes might need to be done in the api as well ) . Much like the one that Atom has.
I would like to have these features because more often than not, I am working with sidebar closed and with multiple technologies - for example LUA embedded in a C++ Container which also contains HTML/CSS and JS. Having icons at the top bar will easily help me to identity which type of files are open very quickly instead of gauging it from the syntax .
Having an advanced (yet stylish) autocomplete dropdown would help me to easily identify the type of the item in the dropdown (if its a method, a variable , etc) . Another example of the advanced Autocomplete would be the parameters that a function that i chose in the autocomplete is expecting.
