ideas for the future

date parsing and more
drag and drop export, which got easier since I change the db
client file-sync over several computers
ssl
i gotta rewrite the db access sometime, to make it mono-threaded
*booru searching and downloading
session management, so access keys are not thrown about so much
(given session management) http login form or background javascript so browsers can load images straight from a file repo
develop Hydrus CopyScan Technology™® to ensure no one ever ever violates copyright law®, ensuring intellectual property jobs stay in America, #1!
better download management
UPnP for auto-NAT traversal
(optional) key regen, so users can change the key their account is linked to
cleverer downloads, with http resume (setting up support for larger, non-image files)
better and more granular pending management (I've done this for tags, now need to do files)
download rules (a bit like rss), so certain-tagged and -propertied files are automatically downloaded
messaging system, so users can talk to admins (and perhaps vice-versa)
hierarchical sync, so lib can sync files/tags from another version of lib
compiling statistics on users' files and submitting to a central repository, access to which I can sell to advertisers and market research groups
more view types, not just a grid of thumbs
mouse gestures? wx seems to support them, but I don't know how good they are
completely bug-free animated gif rendering (lol, not likely)
tag synonyms
text (as in documents) support and display, maybe through web browsers looking at a local lib server or plugged-in web browser tech. not sure yet
And much, much, more! My to-do list is perpetually overfull.

a looooong way into the future

audio
efficiently-packed short animations with synched audio (noisy gifs)
video
3d models
other social stuff

never going to happen

give you up
let you down
facebook integration
in-software advertisements/spyware/bonzi buddy
making things noob-friendly at functionality's expense
