Someone mentioned this long time ago, so this isn't entirely original, but it certainly would help if there was a button which updated the control on the Form with the settings that are defined back in the BO.
Currently, this field shown in the image has to be deleted, then re-inserted if the "model" or the "defaults" are out of sync.
Of course deleting may shift the form (causing more steps to fix this) so an ability to update "in place" with a simple click of this button will really make things easier.
Will really help if someone is interested in this to contact Vlad directly, rather than just posting +1 here. That doesn't always help.

PS _ the other thing that was mentioned a year or two ago was it would be nice if you could also push the default BACK INTO THE BO... so you've done some fine tuning to the control here on the form, and you really want a "one-touch" way to save the numerous properties rather than re-apply them one by one (which, as you know, usually take 2-3 tries to get everything "just right" back in the BO model)
