As this was our first try to develop a TYPO3 extension and it was written for a specific conference, there are many things to do at the current alpha state to improve it step by step, striving to get a more generally usable conference extension and to do a better TYPO3 integration.
improve the underlying database design and coding (e.g. linking billing data to an order instead of linking to orderer data, generalize product handling, handling online orders as accounting entries, release the bindings to special UIDs, find a better solution for fe_groups adjustment etc.)
integration of multilingual capabilities and editable text messages/labels using locallang files
integration of extension specific CSS styles
improve TYPO3 CGL compliance, implement the TYPO3 DBAL to support other DBMS than MySQL
implement an attendee registration interface comparable to the existing speaker registration interface (static template)
find a better solution to handle UIDs and PIDs of the database table fe_groups (fixed UIDs, manually PIDs adjustment at the moment, see Configuration), e.g. make fe_groups UIDs changeable via Constant Editor
implement different configurable VAT rates, develop a generally available VAT ID check (see Known Problems)
develop an automatic mail generator to send reminder mails to users (e.g. respective payment)
develop a conference sponsor management (e.g. for attendees who receive special discounts)
