2 - libpnd: merge overrides, fix it up;
3 - full-replacement PXML is one option, another is
4 - apply override to all sections that match -- by unique-id, so apply override to all sub-apps that apply?
6 - libpnd: appdata-dir-name
20 - Makefile change for building with sdl for djw?
22 - tell ED how to launch it
27 - status-line at bottom; number of categories, humber of apps found...?
28 - menu hint text (hit "menu")
32 - pick/rotate category
34 - honor render_mask to know what to update
35 - defer icon or preview-pics
38 - add callback to pnd_disco_Search (maybe new func to not break cpas code), so can show number apps found so far
