Sticky filter and multiple quests and arena

I have suggestions for the game:
1. Sticky filters for champions: as currently implemented, the filter are mostly useless outside upgrading champions. Please make sticky filter in other areas of the game like arena. For ex, if I want to play with 4* only, the filter (and sort) should stay in the next round champ selection. I'm tired of re-applying filter. Also sticky filter for items in stash.
2. Arena: just one button to request help to refresh all used champs at once, not one-by-one like now.
3. Multiple quests at once: can play main story, event quest, daily quest, all at the same time, provided player uses free champs. Only one quest of its kind, though, so can't do 2 daily quests and different level at the same time, for ex.
