Yes; we’ve neglected to write the documentation for custom.ini so far. It’s somewhere on a to-do list 😉
Basically; create a file called custom.ini in the same folder as CCEnhancer. Place any winapp entries into this file that you wish to use, but aren’t part of the winapp2.ini file we ship.
When you update using CCEnhancer; all of the entries in custom.ini will be merged with the updated winapp2.ini file automatically.
As for Trim.bat; it’s something we plan on adding.
