Mobile bugs and recommendations

I have a few bugs I'd like to put out. I play on mobile and my device will crash alot due to particals I would like to control the particals like on the java edition. Another thing that keeps happening is that when i join a friends world At spawn I'm usually missing a 16*16*16 block sometimes this bug will suffocate me and my stuff will stay at the bottom of the area. Lastly I would like to see a few more chunks out other than 6 and 5 and maybe some huge performance. If a staff is reading this please don't work on this during the holidays. Thanks if your considering fixing these bugs.
