Steps to reproduce:
- open QC from command line by passing multiple python files at once
(e.g. generated python file list from pyside repository or similar..)
- from inside QC use File -> Open File or Project...
- select multiple py files at once (e.g. select all python files from Python's lib folder)
I think QC checks for each file the language client stuff (is pip there? has pyls been installed?) and this is happening blocking - IIRC you promised to make this async - so, please do for the next release..
