TabsFolders is the only app/service I bought on AppSumo (and I bought a lot) that shows me a message regurlarly that I should upgrade to use these features. Ik need more codes to activate these options. I already bough more codes to get V2.0 and was able to use the SMTP feature, but now it's disabled again. All features and things on the roadmap should be lifetime, like all other apps/services I bought on AppSumo.
