you are right, I'll keep the encryption feature in my mind for some future
version. Regarding the management of the different object stores I am a bit
stuck wondering how to put that into the tiddlywiki archtitecture best.
Perhaps you have another good hint for me ;-) Hope I'm not to annoying with
all that questions... Here's what I'd like to to:
- execute the window.indexeddb.open function (e.g. from startup of from a
macro)
- in the "onsuccess" callback for that function: read all objectStores and
list them in a ControlPanel tiddler (adding buttons for move/delete on each
item)
- from the buttons: execute some javascript to do actions on indexeddb,
also including callbacks which should then refresh the tiddler.
I'm not sure how to integrate all this async callbacks. Perhaps you could
point me out the direction? Are widgets want I want or is that not the
right thing? If I understood it well, the messaging should help me, but I
would have to work on the DOM directly, right? I was hoping I could just do
some simple macros, but that wouldn't work at all with callbacks probably...
Secondly, I wondered whether at startup the plugin might delete any

No worries, such a project is a good way to learn a lot about the
tiddlywiki architecture ;-) I made a startup module to clean up the
indexedDB, that's working fine now. Thanks for your hints.
Cheers
