[Filtering] Enable free-form text filtering for requests & logs filtering

[ialexivy]

Not an issue, rather a feature request, please enable a way to filter requests (like in chrome devtools),
it's a mandatory feature for both requests and logs.

Thanks.

Thanks for the request @qwerty789!

Request filtering is something we've been exploring. I'd love to know a bit more about what, why and how you'd like to filter requests.

As far as log filtering goes, I've got the same question: what, why and how would you like to filter? But also, I'm interested in knowing a bit more about your usage of the current logs filters. Do you find them useful?
