I often create quite a lot of custom profiles (custom modpacks) to play test certain mods and at the end of the day I end up with a bunch of custom modpacks with the same image and look. I have no other way except reading the Title and Minecraft version of the modpack to tell them apart.
I propose the following suggestions to improve the creation and management of personal modpack:
The ability to change profile pictures of custom profiles
(custom personal modpacks)
Being able to change the UI color theme inside/outside of the custom modpack (a set of standard color palettes presets and being able to create your own color color UI theme)
Being able to filter modpacks based on alphabetic order (title of modpack or author), date of creation, last time used and version (All of which can work reversed)
