Double clicking the tab bar and minimap bring up the Open file dialogue. This doesn't seem correct to me; is there a way to configure this?
If I double click an empty area of the tab bar, I would expect a new empty tab to open, like is done in Opera and Firefox. Opera also allows for a middle click to open a new empty tab. A text editor is fundamentally different than a browser though, so a fast way to open a file should probably remain. I would accept middle click opening a new empty tab, while double click prompted to open an existing file, or the other way around.
Sometimes when I am clicking through the minimap, I click too rapidly and the Open file dialogue appears. I think the minimap should ignore double clicks.
