I use two profiles of console: bash(normal) and python. I think It could been great to don't must worry about switching between them.

Thanks that we can allow Konsole to using custom desktop associations(actions based on mime type or something of dropped content).

It could fix also Konsole and Dolphin's integration. Actually we had very bad situation, when Dolphin send to STDIN of Konsole cd $PWD . In future Dolphin can only use Konsole associations to drop current directory and do the same once Konsole profile was changed.

How would konsole know which profile you want?

It has been two weeks without comment. If you still want to make this idea, please answer the re-post, answering the questions asked.

Konsole would switch between profiles by recognition of ranned(foreground) program.

That wouldn't work, because when you start a new session it re-runs the program, so any action you take when running the program wouldn't work. Further, it would screw up stuff like running "python .py", since it would cancel the execution of the script. So I'll move this to wontfix.
