I may be missing something but using "Commit and Push" in IDEA 93.83 doesn't really pushes the changes to GitHub repository, I need to later run "git push origin master" from the command line.
Here's what is displayed in console window when I click "Commit and Push":
13:26:59.516: git commit --only -F d:\Temp\Win\git-comit-msg-7368855630549575609.txt -- src/widefinder/Start.groovy
