I utilise a lot of these frameworks, and the examples mentioned above are just one of the many available. One area of framework which I often would like to use is a UI framework for building interfaces. There is jQuery UI which is a very comprehensive framework but having looked at it I find it a little too bloated.
There are plenty of widgets available which makes it easy and quick to develop a consistent set of forms and tables to display and manipulate your data. There are buttons, tabs, menus, messages and even a handy grid system for your complete UI. I have used it recently on a big CMS build and the results were excellent.
There are a few missing widgets which I would particularly like such as a date picker, but these aren’t too hard to plugin from elsewhere. Also there is a robust roadmap for the framework so I expect things like this to be developed soon.
The CMS I built was based on CakePHP which has a number of in-built helpers which make it quick and simple to build forms. Integrating Twitter Bootstrap with CakePHP wasn’t that hard a task but it doesn’t work out of the box. The markup patterns for the helper and bootstrap weren’t compatible. Fortunately the helpers on CakePHP can be highly customised, its not easy but also not a big task.
I aim to release a plugin helper which will make this a lot easier. It will replace the FormHelper and provides some extra methods to output of UI elements. I’ve been very busy recently so haven’t had chance to write it yet, but look out for it soon on github.
