Since only a few people donated something for my Launchers in the past years I am trying a different approach with ESO Manager (ESOM). There will be a completely free "Lite" version with all the basic features. Without annoying popups or reminders to buy a full version. But if you like it and want more of it you can go Pro and unlock additional features for a small one time fee. (This should conform to the rules of ESOUI where only free addons/tools are allowed?)
(this is just a mockup - no final numbers!)
