They should have preferences. It would be cool if hopscotchers have options, such as:
Changing background screen from the off-white to some other color, like black (awesome for nighttime, this is something that already exists in awesome-e’s webplayer)
When selecting a block, the ability to keep the block selected even after replacing it with a different block
how many projects are in each row (like changing the size so that there could be more / less projects in each row, kinda like what awesome-e has in his hopscotch webplayer)
the order of the tabs (I would rather the following is first tab rather than somewhere in the middle)
These are the ones I thought up from the top of my head. If you have anything else that can be added to preferences, feel free to state them! I didn’t check if a topic like this already exists, so sorry in advance if it does.
