ChiliProject is not maintained anymore. Please be advised that there will be no more updates.
We do not recommend that you setup new ChiliProject instances and we urge all existing users to migrate their data to a maintained system, e.g. Redmine. We will provide a migration script later. In the meantime, you can use the instructions by Christian Daehn.
Autocompleted fields (Feature #464)
When creating a new issue, most fields are drop down. I'd suggest going with something similar to Jira where you have the possibility to still use the drop down, but also have the ability to auto complete typed text.
This would require validation of typed text (make sure that the value exist within the list).
The goal here is to be able to support larger lists. As you can see from ChiliProject's own category list, it is long. This is also the same for the Assignee list which could be very long when you have many employees which can have a task assigned to them. It would be much easier and quicker to be able to type it in instead.
