You can favor modules if you are a Unicorn member. That way you get a tab with only the modules you've starred/favored and can browse through them at will. Super useful! I use that to see only modules that I actually own :)

When using the Module Finder (re: list of modules) one of the options is a small briefcase. Use it to add/remove modules from the My Modules tab. The tab can be found right on top of the Module Finder, right next to the All Modules. You can switch between browsing all the modules, or just the modules on My Modules.

Enjoy!
