Just this morning I tried to make Outlook on my work laptop to open on startup. I have to find and add a shortcut of Outlook, buried somewhere in the machine, to the startup folder, buried somewhere else in the machine. The startup apps settings menu was just an eclectic list of programs and is of no use at all.
With Mint on my home machine I just go to startup programs settings menu and I can add whatever I want just by pointing it to the right program. It just works.
