ProdUI: For a file selector window, I got the basics of a menu with columns and sortable categories along the top. You click the category and it re-orders the menu items according to a sort callback function. You can also drag to resize the columns.
Started on a couple of markup-to-formatted text libraries. The first was originally a GemText parser + display lib, so it’s line-oriented. The second works with tags, similar to richtext, but with some more steps in the pipeline from markup to displayed text.
