I think I see what you mean, but am not sure. I could be wrong, of course, but what you are suggesting would seem to be of limited potential use to most users.
...Having said that.. It wouldn't be such a crazy idea to make a standalone tool of a different name, like SimpleTextFormatter which basically was just the text formatting functionality of chs, designed to be run manually or via commandline.
-have you considered bundling those AHK text formatting commands into an AHK script (or compiled as a .exe), giving it (say) a GUI for the user to select which commands they want to apply? The script could then be called by FARR and used to edit the text contents of the system clipboard or the CHS clipboard buffer (if those things were possible) or a designated text file where the text contents of the clipboard had been saved.
This could be more easy to use for most users than (say) them having to know how to invoke the separate commands individually, or (say) @mouser
having to program in some text manipulation commands which might be of only limited use to most users. If the AHK script was compiled as a .exe, then it could presumably be packaged as one of the many optional plugins for FARR, and it wouldn't necessitate users having to install AutoHotkey.
Just a thought. I don't know how practicable that might be.
