[feychou]

Bugs

• Download arrow is not correctly decoded
• Thought bubble is not resizing
• Menu jumps when changing toys view - give toy a max height of 80px
• On iPhone the controls are slightly too much above the selectables and it creates a double border bad effect

Improvements

• Svgs for icons (to be used in any case)
• Make menu disappear after some seconds of idleness
• Enable swipe
• Do something about the quality loss with Android downloads
• Circles need to be even smaller
• There should be at least three selectables besides the clear button on mobile sizes
