Right now the order of the categories in the Property Editor Tab is predefined by the software and it cannot be rearranged. This can be a nuisance when using smaller monitors or when there are a lot of properties to an element, where you have to scroll down to find the property of interest.
The idea is to be able to rearrange the categories in the Property Editor Tab. This could be added to the Property Grid Customizations functionality. It is already possible to make custom Property Editor Tabs using Property Grid Customizations. Also being able to change the order would be a good improvement.
