Feature request: Filter lines by string or regex matching

[ultraon]

Hello, thank you for your efforts! Could you please integrate the feature Filter lines by string or regex matching?

It's far from perfect and needs more testing, but I have implemented a barebones version of a string filter at my fork of this project.
