This is not a priority for any team, but it would be good to replace current jQuery UI-based widgets in default wikitext editor (WikiEditor, WE) with OOUI-based reusable components from VisualEditor (VE) for two following reasons:
- Feature disparity. The interface for inserting a file is far more developed in VE in comparison with WE, search and replace interface is reportedly the same. WE users can benefit from having features like file search and autocomplete after converting to OOUI and reusing code from VE.
- UI standardisation. Currently WikiEditor uses both OOUI and jQuery UI: jQuery UI is being used in all widgets, OOUI is being used in the styling of buttons and in file upload interface. TemplateWizard beta feature also uses OOUI instead of jQuery UI. With jQuery UI being somewhat deprecated in usage, it would be good to remove inconsistencies.
List of components using jQuery UI:
- Insert a link
- Insert a file
- Insert a reference
- Insert a table
- Search and replace
Not every interface, obviously, can be replicated from VE one to one.
These will be, in my opinion, pretty uncontroversial changes, as their deployment will increase usability of the editor. Maybe then something similar to T174119: Fix several design features of WikiEditor and CodeEditor to match the general style can be done, as those stylistic changes also seem to be uncontroversial after changing all icons to OOUI in T191031.
