The System -> Preferences -> Sessions capplet has had a small makeover for Feisty. Sensible names are now displayed for startup programs (rather than the full command as before) and the Session Options tab is limited to two simple options.
This isn't much of a change in itself - I imagine that session management is still confusing for less experienced users, who most of the time probably just want to make a program run automatically when they log in.
The Current Session tab is still busy and complicated. There's the strange 'Style' column, which determines if an application is started or not at session startup, and integers for what I think are the startup order. This could all be much simpler, as could the method for entering a new startup program. You can either type in a command or browse for one (like a file) in your Home directory! Why not just use the application list from the Alt+F2 run dialog?
So this post isn't really a feature report, it's a moan. But at least things are improving - who knows, maybe next release cycle it will improve to the point of being usable for non-nerds?
I think I'm off to file some bugs.
