I'm using Kubuntu (Karmic) and KATE is my favorite editor. I don't enable many plug-ins, but I really like the inline shell.
The problem is, across re-starts, KATE seems to forget that I enabled this plug-in. I've checked across all sessions and the behavior is the same.
Is there some easy way to fix this?
This is a bug with Kate. But if you disable the session auto save, it loads the plugins. You can do this by changing the Application Startup Behavior to Start new session. Application Startup Behaviors can be changed from Settings > Configure Kate > Sessions. This is not a fix, just a walk-around.
