The text boxes do not immediately get focus to not break user's hotkeys.

A hotkey can be added to make the edit box get the focus, like in #8908. Of course it could be in a separate commit or PR. :)

Seems to me that the hotkey can be rolled into this PR, probably as a separate commit

There you go!

Hi devs, could you make a deployment so people can test this feature?

NewGRF often put some extra properties/text into the panel below the list.
How about the filter would check multiple texts:

• Vehicle name: search for "bristol"
• Refittable cargotypes: search for "coal"
• Extra NewGRF text: search for "freight" (as used in "type of service" in the screenshot)

Responding to your request on IRC, I tried having it below and I gotta say I don't quite like the way it looks

Regarding adding the other stuff for the filter to match, it's quite a bit of work, for cargo types a similar approach to ShowRefitOptionsList() needs to be used, and for NewGRF I tried a similar approach from ShowAdditionalText() but most of the strings ended up with "(undefined string)" on them, I am not sure why. I would love to push these new requests for the filters to a separate PR if that's ok for you.

Hmm, a text filter for cargo-refittability is probably a bad idea after all. It won't work with build+refit, so would readd the old confusion about that.

Yeah I kinda agree with that. What do you think of the filter in a third row vs with the rest above?

I agree that filtering refittable cargos is not a good use of this filter. There's already a drop-down for that.

My concern with the current implementation of the filter textbox to the right of the cargo types dropdown is that it makes said dropdown very narrow. Long cargo names (such as in Paints & Coatings in FIRS 4 Steeltown) are cut off. The full row textbox in the most recent screenshot isn't particularly attractive but it does avoid this issue.
