Move brave://adblock/ to brave://settings/shields.
In the Shields panel on the Settings page:
Look & feel section is moved to the top to include choosing Shields default viewShow the number of blocked items on the Shields icon is moved above choosing Shields default viewCustomize tracking filters is added as a line item underneath Block cross-site trackers
Clicking on Customize tracking filters shows a drill-down page that contains the functionality of the previous brave://adblock page:

Regional and specific filters now have a one-line description underneathCustom filters now have a one-line description underneath where Adblock Plus syntax links to https://adblockplus.org/filter-cheatsheetBrave tracking filters links to our adblock wiki page https://github.com/brave/brave-browser/wiki/Blocking-goals-and-policy#lists-usedFilter list content will be cleaned up in https://github.com/brave/adblock-rust/pull/79
After the user clicks on "Add filter list via URL", a form field appears with "Submit" and "Cancel":

Built-in error validation for the field specifies entry must start with https://

Submitting the filter list URL will add the filter list to a table with a toggle to enable/disable and available actions:

If the user enters a filter list that is invalid or unavailable, the table entry shows the filter as Download failure with no toggle available:

After the user enters a custom filter in the textbox, a saved timestamp appears when the custom filters textbox loses focus:

The timestamp shows relative time for last saved..ago:
mm/dd/yy 00:00

Dark theme is supported:

I'd love to make a nicely formatted copy of this cheat sheet on our Help Center. I feel like we should be linking to our own sources as much as possible (even if "our source" is just a reformatting of something that already exists).
Will write up a draft and share here if interested 馃憤
@karenkliu Can you update the design section as it relates to https://github.com/brave/brave-browser/issues/9975 I think #9975 has the more recent work.
@rebron Yep, thanks for catching that. Updated!
