Thanks for the feedback. I can definitely see a pattern over the last few days. Yes I do plan to have a mobile version, It was not of high priority but I will try to make it as soon as possible. But please understand that there's simply no way to offer the same experience as on desktop so I will have to make a complete redesign for Mobile and that's why I was not able to provide it right away. Even this versions runs on Android (tested it) but to put it simply put... it's the user experience is just awful (not even okish). I mean... the whole UI opens in a webpage and it's extremely complex to do anything because it's to small... some things might not work as expected because of how mobile interaction works and so on...
What that mean... definitely I want a mobile version, but since I need to rethink the whole UX (similar to most mobile apps) it will take a while for it to happen. (Or maybe not that much but can't really make a promise at this moment)
Regarding the unload option... Yes, definitely a great idea and I might be able to implement it pretty fast (if the API does what I expect).
Feedback is really valuable for me so thanks again. Also, thanks for raising the rating to 4 from the initial 3 (that's what I've seen in the mail) and I hope that once some of the new features you're waiting for will be implemented you will remember about this feedback and maybe reconsider it for a 5 star :D
