NOTE: This is still a work in progress but I plan to have it ready for release next week.
So far it is working for all the main property grids except those in reports. I am very excited to have got this code working and I think it will be a huge productivity boost.
The property grid state is saved on a per "context" basis. This means that, for example, all buttons in the window designer will have the same expanded/contracted categories in their property grid. Same with lists, prompts, etc.
This week I will be concentrating on stabilising and testing this new feature as well as making sure it also works in all areas of the IDE! If I get a chance some other ideas are: expand/contract all buttons, filter grid items, hide grid items.
Here is a short video showing how it works.
