Factoring name pattern when checking mod existence

[strdsk]

The problem

I'm using MultiMC and as you know, it has mod disabling features, by suffixing .disabled on file path. The problem is, I need to reenable all mods to prevent ferium from unnecessary redownloading.

My solutions

Add options for user to add patterns to be used on file check besides the normal checking per profile basis?. Optionally, add something like ${MOD_NAME}.disabled by default, fixing this problem for MultiMC users and at the same time an example for end user.
