A new, remodelled dialog, much more square-like and in particular no longer needs to dock or scroll. All 6 keyword lists are on the same tab now, and one can drag and drop text between them.
Style changes are now made through a modifid system font box, which is spawned by auto-styled labels - not true for the keyword lists, but they are optionally styled anyway.
All dialogs, even ephemeral, have translatable titles and labels. This could be extended so as to make the localisation more powerful, while uncoupling it from application structure.
