Open file does not ask to save current file, it simply overrides it

[CriPstian]

Hello,

this is an issue that I encountered and I think should be fixed.

Issue Description
Opening a file does not prompt user to save the currently modified file and it looses unsaved data.

How it should work
When the open file action is triggered and the current file has unsaved changes, the user should be notified about this and given the opportunity to Save, Don't save or Cancel to go back to editing the file.
Current work should not be lost without user consent.

thanks
