If You're Going To Market It As 'Pro' At Least Add Some Basic Editing Features (crop, split, image adjust, effects, trim - not by keyboard entry but sliders)

I know of a couple competing products that have the same general features you have on Media Converter "Pro", (their interface is almost identical too - hmm). But they also include the ability to trim, crop, split, merge, adjust color saturation & hue, adjust brightness & contrast etc, and add simple effects). And by trim I don't mean having to guess at what points in the time-line you want to start and end because you can't do something as simple and common as PAUSE the video. But use the common standard in multimedia editors which is slider IN/OUT points across the bottom and the ability to PAUSE the video and select "Set As IN Point/Set As OUT Point".
