Hi, I just installed Celena. I had been running Cassandra since it came out, so I'm pretty familier with mint.
However I'm still a n00b with some things. Anyway, after doing a clean install of celena I noticed that programs that I tell to have a panel icon (deluge, exile, etc.) the icon doesn't show up. Even for mintupdate or any of that. Only the icons that I manually add show up (workspace switcher, clock, and network status)
