I'm happy to hear that the next VS ASP.NET designer will be huge!
It will fix some stuff and bring nice value additions to the poor actual VS2005 one :
- Split View Support (the ability to have both HTML Source and WYSIWYG design open simultaneously)
- Extremely rich CSS support (CSS property window, CSS inheritance viewer, CSS preview, and CSS manager)
- Dramatically improved view switching performance (moving from source->html design mode is now nearly instantaneous)
- Designer support for nested master pages : this is a must-have, and certainly the main reason why nobody use nested MasterPage (and yes, I know, solution exist but...)
