[Suggestion] Make DevTools GUI more "rude"

[ds1709]

Current DevTools UI is (IMHO) inconvenient in some aspects. This aspects slowing down development process. Here some of them that inconvenient exactly to me:

• To many blank space. Working with properties list requeres to many scrolling, in particular, because of blank space between properties. Elements margin is to high. Better make it more compact.
• Some property editors, like margin/padding editor, requeres many motions because of input each part separetly. If you want to set all fields with same value, you have to input it four times. Also, it will be more usable with single field.
• Property groupping can not be disabled. Even when I sort properties alphabeticaly, they a still groupped, and it makes navigation it difficult.
• Selecting element in tree reset current property list display options. If I select alphabetical ordering, changing selected element in tree reset it back to original.
