Finally, we have an early version good enough for everyone to
start banging on to help us polish it up and find bugs.
Please take a look and file bugs in the bug tracker under "Database module".
We urgently need
- new icons for existing field types
- testing on PostgreSQL install
Coming soon (?):
- Many more field types: calculation, checkbox, relation, date, datetime,
time, email, group, list, user, number, richtext
(Please let us know if you are interested in developing any of these)
- A way to save and restore "presets", which are field/template sets
- Backup/Restore support
- Groups Support
- RSS support
Many thanks to Yu for all the hard work under my whip.
