Like a macro replacement or something, doesn't matter how configurable it is, but I'd like to just be able to set $MY_APP_SERVER = '192.168.0.100' or something and then i can use http://$MY_APP_SERVER:port/url in each of the application buttons.
I just had to change the address where everything in my system points to, and Heimdall was the only pain point I had in doing that, everything else was a simple find/replace in my configs.
