Hi,
Here are the things I think is needed to apply to the Form Designer:
* Just like module design in form section please change "Saved!" dialog box to a "Saved" style in module style, It's annoying to move over and click Ok button each time you make minor changes to the form.
* Ability of Copy, Cut and Paste on controls is necessary - specially when you want to put many big controls (for example RichTextBox) from a designed form inside TabControl - that's nightmare.
* CTRL+Z is a must! you accidentally delete a control, you have to drag it to form again - imagine you've set lots of properties.
I'll add if I got something new...
