When editing a mod's config, it's often required to tweak the config, close the menu, interact with the game a little, then go back into the menu and tweak the config further. When you open the menu to go back the make further edits, you have to type the name of the mod you're configuring again each time because the search bar doesn't remember the most recent entry. If onerous, this feature could be togglable.

Thanks for the suggestion. I've added the feature in 3fcc8ed
