"What's the limitation that you have come across?"
Currently the reports that the Linter extension generates as a Special:LintErrors or it's subpages, are a single mass set of results. For a site where the content is largely per page, this is reasonable...
However on some wikis (including Wikisource), subpages are used extensively. This means to identify all the pages of a particular group of pages and subpages where there are concerns means searching through the entire results set (which could be several hundred results at present). This is not necessarily an optimized workflow.
Also the Page: namespace (on wikis where Proofread page is installed) is (at present) typically implemented as Page:<name of work>/<pagenumber> which the Linter extensions seemingly treats as a single title for each Page, as opposed to grouping all the pages for a particular work
"What is the functionality you would like to see implemented?"
- Implement a search "filter" (as utilised on other Special:pages) so that the results can be trimmed down by a relevant prefix.
- Provide an appropriate UI component in the relevant Special:LintErrors pages to allow a contributor to specify the prefix to be used in limiting the results displayed for any given Linter concern/error..
Longer term, additional filters could be considered (such as limiting it by pages edited before/after certain dates, or solely by the contributor... much like the filters that can be applied to other Special: pages )
