There is really only one improvement I would love to see.
#1. Printing support for Linux. Currently, v14 and I assume v15, the linux printing support is 100% total junk. In every other product for linux, when I print, I get a printer box where I can select the printer, and options etc. For SE, I see not that, but a CUPs SINGLE line entry. What a joke. I have to use, get ready for this, GEDIT to do my printing.
Come on guys, please fix this!
