Few issues

You app is really awesome! I've never seen such user friendly & well designed todo app yet. However as a front-end developer i've noticed 2 issues

1. It's hard to hit icon to expand substatsks on mobile devices. https://monosnap.com/file/qCySAUJvMQ2878WzLgaWrGM0PpRM4H Button with this icon should be larger. You can make its size 30x30px instead of 16x30px. Square buttons for icons are more convinient to use.
2. https://monosnap.com/file/ZnglKzChWfq0uPYHtJEzWFYkNXAKI2 When i click "recent activity" the first time, animation seems to have lags, when i click another time everything looks good. It coses because "activities ulist" is empty before animation starts the first time. And height which is going to be animated has calculated before you put activities to list. Then animation starts and you put activities in the list at the same time. When animation is done the ultimate height suddenly is different from wich had been calculated on starting animation. That's why you can see this lags. If you put activities in the list before starting animation, there will be no lags and animation will always be smooth, which is supposed to be.
