For Windows based software regarding image processing, I am torn between two options for grouping logically similar parameter controls.
The option on the left is more thrifty with screen space, which is a consideration in this case, but I can not form an opinion on which option is more convenient or understandable. I think the groupboxes (option on the right) might cause unnecessary clutter. On the other hand, the group titles for the option on the left may look too much like buttons, which they are not.
Which option is more 'correct' and why?
Also, this is my first question on UX and am unsure what to tag this, please advise.
