change GridView to PinterestLikeAdapterView by DGD in Korea
bug - margins are wrong and look ugly
add ScaleImageView by maurycyw, which makes the posts expand to the
→ image size as soon as the imaeg is loaded. This has a ton of
→ advantages, but its biggest disadvantage is that I now need a
→ special type of List-/GridView which allows the posts to have
→ different heights
remove a shitload of code I can't use because of the new Pinterest thing
remove functionality which saves list position (state) which is sad :-(
