Lately I had my iniBuilds password changed. My iniManager remained logged in, but I couldn't make any purchases anymore because the stored password was incorrect. So I figured I'd logout and login again but this wouldn't work, there was no way to logout on the iniManager. I ended up deleting the cache or whatever it's called, giving iniManager a fresh start. Then it asked me to login and I was able to login using my new password.
So the feature I'm requesting is a logout button on the iniManager as what I did is way too complicated and I feel like it shouldn't be necessary.
