If I double click on a file of an unkown filetype I get asked to specify the type of file.
IDEA then scans project files and even the JDK for this filtype before opening the file.
It would make more sense for the file to open in the text editor with the text highlighting as specified by the format chosen
THEN the scanning should start in the background
The scanning for files shouldn't be interrupting my workflow, especially if I am essentially just opening a text file
