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
8 - wrapper black screen?
10 - conf: use real app searchpaths
12 - redraw after deferred preview load
16 - tell ED how to launch it
20 - pick/rotate category
22 - honor render_mask to know what to update
23 - figure out why deferred preview pics blow up
24 - handle SD eject/insert
28 - add callback to pnd_disco_Search (maybe new func to not break cpas code), so can show number apps found so far
