Planeswalker Filter

When you go to Planeswalkers from the menu there is a Filter option at the bottom which I find very handy. Any chance of getting this implemented when you are selecting Planeswalkers in an event (particularly when using View All)? I have an older device and if I have had the app open for a reasonable amount of time this selection can slow down greatly. Having a filter here would greatly improve things.

Also (less importantly) it would be nice if there was a checkbox in that filter that allowed your search terms to also apply to the Planeswalker abilities.
