The problem with online courses is that they treat students like children. When Lingvist was in a navy theme I really liked the minimalistic features of it, no 'daily goals', just stacks given, and I repeat accordingly, I think every old user would miss this simplicity at least once in a while.
Is there any way for you guys to add a rollback button upon request? Or better, customization, I don't need my 'progress' part, and I believe it's not only me to be an independent learner who doesn't really need a tacky motivation bar or daily goals. I'd gladly pay for the service you used to provide, now it looks like any generic language learning app.
