One instance Kate
Kate is a wonderful editor for fast editing php (css, js whatever if is text) files. Recently after upgrade to Kubuntu 9.10, I started to get disturbed from multiple instance of kate. What means is when you open a file from konqueror, system opens a new editor, instead of using existing instance.
I thought to solve that simplistic problem inside of kate. But there is no way. incoherently there is sessions. I never get use them, like konqueror's profiles.
Solution is enter system settings ->advanced tab ->file association
find kate what ever the filenames we deal with application then edit kate
goto Application tab
enter kate %U --use for command.
The "--use" keyword prevent kate to start if there is one, and file you've opened will happily open in the active kate instance.
