I would even forget that I have any.do if it were not for the widget. I´m to lazy to open it every time to see if I forgot something, so if it doesn’t have a way to tell me that I have things to do outside the app it´s useless at least for me, I need something to annoy me and make have psychological tickles every time I use the phone.
It could have a huge horizontal led line or something, it wouldn’t look that ugly and they could link it in a circuit with the camera so it would require hardware modification to get rid of it. it´s not practical but in the case it gets forbidden (and it will), this could could help…
