For example, if I want audacious to open application/x-ogg files in a new playlist, then I should be able to set the handler to "audacious -E" so I don't destroy a previous playlist, or perhaps "audacious --sm-client-disable". Similarly, not all applications will take a filename on the commandline: some might need "foo -f <filename>". Or perhaps "nice foo -f %s" etc. As it is, I can only use applications that do not need options. Reproducible: Always Steps to Reproduce: 1. Go to "Edit / Preferences / Applications" 2. Select a file type, and try to specify an application that requires a commandline option. Actual Results: There is no way to control the helper program. Expected Results: Let me enter a commandline, not just the name of a binary. Or perhaps add a column for options. Workaround: create a one-line helper script for each such application But that's more of a hassle than necessary, and I'll end up with lots of random one-line scripts. Messy and annoying.
