No, don't call common.default.display_... from n810. The point was to override them. But now that I think about it, I might change the overloading handler code in powerlaunch. Instead of only executing the one handler, it could just execute all, unless a special action is called to stop execution. I'll have to think about which case (overriding or chaining) is more common.

About the language, that's kind of funny given how this thread started...In fact, i purposely tried to simplify the core language as much as possible. I didn't want a full language so nested ifs and command blocks will likely never be implemented as it can be implemented in other ways. Logical expressions are likely to be implemented as I'm thinking of moving all of expr into powerlaunch. Note that you should be able to use expr to do logical expressions currently like if `expr $foo | $bar` ...
