At the risk of touting the competition, I find the capture bar of FScapture to be by far the easiest to use. It has a (configurable) row of easy to understand icons for each type of capture (e.g., entire desktop, active/current screen, user defined region, scrolling, - - -). Using a drop down menu for these options adds an extra step.
I notice a general tendency of programmers that is increasingly frustrating for me, as a user: Packing more and more options into an application. Each user interface is always a little different. So for each new app., I must learn to navagate a new set of menus, hotspots, hotkeys, settings - - -.
This had been solved for a time when Apple and Microsoft adapted a relatively standard menu interface for everything whatsoever. But this seems to have broken down. Now, so many new whatevers seem to have new looks and feels.
