Nice to know Palm writes hacks, of course when Palm does something
like this it is called something like elegant programming :).
I definitely do a rename, so launcher might display the new name
instead.
As I noted 3.3 already does this (a webclip icon won't disappear).
I'll have to give it a try. Maybe I could get launcher to bypass my
preservation mechanism. If I rename a DB or change its type within an
app, Launcher should pick that up.
DmDeleteDatabase is only passed the LocalID, so I wonder about the
name.

Name and how many attributes? Just the name? Type and createor? the
attributes themselves (launchable/stream/etc.?).
The problem is if it is using localid as the cache entry key, the only
way would be to move each record or resource to a new database, and I
don't know if detach/attach can do this type of thing.
