Improvements? or bad ideas?

I have been playing league for a very long time so I have collected quite a bit of stuff (Champions, skins, summoner portraits etc), and truth be told, it can get a bit messy sometimes. I feel like we have some things implemented to really help us players to organize all of this but I also feel like its only halfway implemented at the moment. For instance when you made us able to mark champions as favorites it became much more easy to look over the champs you like most and decide which one to pick according to how the champion select was going. However we are only able to mark champions while in champ select. I feel like this takes away from the mechanic itself because champion select can be quite stressfull with all of the things you need to do while in there, making the mechanic itself underused and forgotten since its not as important as other things you need to get done in that short time. If we instead could use the profile page in the client somehow to do these changes I feel like it would be a much more used mechanic and would help atleast some players. Id also like so be able to hide some of my summoner portraits since i got waaaay too many of them and cant really find the ones I like among all the others.

Also, to make this wall of text even longer I just encountered a fairly annoying thing. I got way too many chests compared to keys, as I know many others do aswell, and today I used my only key on one of my masterwork chests. I got a skin I already own worth of 195 OE. This means I wasted both a potentially really strong chest along with my only key and grinding a new key will take atleast a few days (for pretty much only 195 OE, which i cant do much with since i got no skin shards since I cant get keys to open my chests). You cant guarentee that every player can be content with every chest and you should not do that either, but cant you make the player choose between accepting the skin/champ you got drawn or exchange it for another key?

I feel like that would both remove the grindy feeling of getting keys aswell as give chests a greater feeling overall and would push more people to play more champions at S rank. And it also wouldnt make things unfair or broken because even if you choose to get a new key you would still have lost a chest.

Impressive for all who read this far.. Does anyone feel like anything of this would be good quality changes to the game or am I the only one who actually would like this??
