I can't wait until they expand on it! I have tons of people in my audience telling me they want to tip but can't for whatever reason, or wish they could tip more. (Reasons like "my phone can't handle the app", "the app is crashing", "the ads run out", "I can't have the app because my parents monitor my phone but not my computer", etc etc)
So it would be a big improvement if they'd expand it to desktop and get in touch with peanut lab / surveys and the like. I think adding surveys to free coin earning could kick up the tipping rate big time, and give smaller creators more of a chance too.
I would also like to be able to scroll through the tippers by recent, popularity and name on desktop and not just the app.
The app can be a little weird and vary from phone to phone and it gets in the way. I, for example, can't scroll past a certain point - making it impossible for me to even see all the people that tipped me 1k coins or more. This became a bit of an issue last time I decided to give all those people a reward for their help. Thankfully, a member named "tvgold" offered to help me cause the full scroll worked on their phone.
