10 # To do
11 -- more tests
12 -- permissions
11 - search
12 +- frontend: dialogs
13 - vfs: serve an html for a folder?
14 - "default" property for vfsNode?
15 - sticky breadcrumbs
16 - interruption of long requests if client aborted (searching/listing)
17 +- throttle speed
18 - frontend
19 - don't depend on cdn
20 - webdav?
21 - streamable zip archives
22 - no compression
23 - resumable?
24 -- vfs: ability to remove/hide/rename files deep in a source
\ No newline at end of file
24 +- vfs: ability to remove/hide/rename files deep in a source
25 +- let user change password
26 +- login without passing clear text password?
27 + we could use asymmetric encryption, possibly on a hashed password, that means
28 + we should store a hash2(hash1(password+salt1)), where hash1 is applied on both client
29 + and server, which grants that even if the encryption is broken only the salt-hashed
30 + is revealed, which compromises only this server and not others.
