Time based filter

I use Miro as a dump yard for my brain. That means I keep dumping every now and then.

1. What I would like to do is to have a filter which allows me to do this →  “Hey, show me all that I dumped today” on this big board..

2. Give me a global search , much like how its there on Github. If i search for “lorem”, show me results not only on the board that I am, but also across all other boards that I have access to.

Thanks.
