Scratched a couple more unneeded bits from the mask. Moved mask storage directly into the panels_page table, and updated load functions accordingly.

Killed some more of the unnecssary bitmask items; fixed typos; improved hook_menu() readability; safely reconstituted the panels_page_get_current() function for API consistency from D5.

Considerable refactoring. The separation between logic/loading functions and rendering functions is almost complete, now.

Fixes for E_NOTICE compliance with $load_data. Moved access check to later in the master loader; we don't want Panels denying access to things that it's not overriding!

Removed suuuuuper crufty ajax functions - they hadn't been in use for who knows how many months, and nobody noticed :)

Moved the admin wildcard loader out into the main panels_page.module file (where it should have been in the first place), and rejiggered the paths to match up with the new editing paths (action verb before $panel_page->name). The new paths may be rolled back.

Nixed the wildcards and stored_router fields, and changed 'meta' over to the much less annoying/more appropriate 'flags.' stored_router was collapsed into flags; wildcards may be restored later, but for the moment I don't think there's much value added in duplicating that data, so I'm content to calculate it on the fly.

Fairly large reorganization, although not much change in the logic. Most notable big item is that hook_menu() and hook_menu_alter() are now separate again, and the functions have been reorganized to place the two that hook_menu() calls at the top of the file (purely for conceptual clarity).

Also switched over to the use of a 'flags' field in the router quickref table, which is where we tuck as much of our behavior-governing bitmask as possible during the actual menu build process.

Incremental commit - numerous behavioral changes. Admin loader relocated to here; re-added implementation of hook_menu() as it now appears possible to cleanly separate it from what must be done in hook_menu_alter(). Cleaned up some docblocks, moved other functions around...lots of stuff.

Shifted all possible render preparation functions into panels_page.render.inc; also added an @file description to it.

Just need to get the delete button working and then go through all the contexts, relationships and arguments to make sure their forms are working.

We're most of the way there! Our separate data storage mechanism appears to be mostly working. Now the frontend loading needs to be done, along with the hook_menu_link_alter() stuff.
