Configuration UI sorting, grouping and filtering

It would be more helpful if there was a way to do any of the following in the configuration UI:

(A) Filter only on certain filled-in attributes, such as only those in database, or in .properties file and/or the ability to suppress anything with <NotSet>.

(B) Sort parameters alphabetically. There seems to be randomness in how they are sorted.

(C) Group together all parameters by subclass. ie., changelog.consumer.<consumerID> or subjectAPI.source.<sourceid> params are sometimes together, but some others are way at the bottom of the list, in no particular order. Would be nice to be able to see (or even visually collapse) the list of params specified for a particular subject source.
