Float

Float's user interface and logic are inspirational. They have made the activity of coordinating multiple resources on multiple projects about as easy as it can be. They have paid a lot of attention to usability, efficient use of screen real estate and simple navigation. However the killer feature is the intuitive yet clever way that searching and data navigation work. All searching and filtering is done using a single search field, which offers indexed word search on pretty much everything including tags. There is also a well-worked out protocol for handling union and intersect searches.

The only real bugbear is that any user that can enter data into the system can define new values for any field. It isn't possible to centrally control lists such as task names, clients, job descriptions etc. This means that if you have more than one person using the system, very quickly you get different versions of the same thing being defined (e.g. job roles being slightly different) which makes it difficult to analyse across records. Not a dealbreaker, but I do think it should be possible to lock down lists of values. Also it would be good if you could zoom out the view a little more - if you're dealing with more than a dozen resources/projects.

How easy it is to use. It's easy to jump in and also complicated enough that you can really use some advanced features.

There are of course small issues here and there but none worth mentioning at all. It's truly a great product and really helpful.
