When in Minecraft pe Classic UI was added then crafting and villiger trading was eazier then its now. With this square line around slot make things more difficult and annoying. for example crafting trading, moveing items is way more annoying. Why dis still not fix. This bug appeared a month before first aquatic update beta I belive. I'm useing Samsung galaxy J7 2017 but this bug affects all smart phones including ISO devices. This phot is from Sky trade map and on this map is to annoying to tade with villigers to this annoying square line. Please fix this and get back to normal how used to be on classic UI then that is added to MCPE.
