The easiest way to get video clips into Movie Maker is to tap the "Click here to browse for videos and photos" button in the main timeline area. There's also a permanent Add videos and photos button on the Home tab. Each button opens the Pictures library, where most people's point-and-shoot videos land when they import from camera media. There's also an "Import from Device" choice in the File menu; this just opens the Windows photo/video importer, which actually does a decent job of letting you apply keyword tags and saves the image and clips to date-and-time-organized folders—not unlike iPhoto's "Events." And finally, you can start capturing video from your PC's webcam.
Interface design: While the layout of the interface is clear and functional, the color scheme definitely leaves something to be desired. A lot of the text is in gray or brown lettering on a black background, and some menus are even light gray on dark gray, making them almost impossible to read. There are several skins available for this program as well, and they all have the same issues in at least some parts of the interface.
The T#i line is what they call a "pro-sumer" line, which is basically between a consumer line camera like a very basic DSLR and a professional DSLR camera, thus the term "pro-sumer." Typically what this meant is an DSLR with an APS-C sized sensor, decent resolution, and some hand-me-down professional features of pro-grade cameras from a few years ago. For this reason, sometimes it's not worth upgrading from one of these cameras to the next until at least a few generations have past (meaning if you have a T5i, it's not really a giant leap forward to upgrade to a T6i). However, the T7i is somewhat different. When I was doing research on what features it has and what it is missing compared to the pro-grade DSLRs that are considered "current" right now, I was surprised to find very little. The main differences really is that the pro-grade cameras have the LCD display on the top that would display all of your relevant camera settings, and then a few of them would also sport a full-frame sensor. Other than that, the differences are very minor. Something like maybe 1 or 2 frames less in burst mode or something like that. Nothing that would really jump out at you and make you regret not stepping up to the professional grade equivalent (Think it would be the 77D?). It actually has pretty much all of the big features of even their current pro-grade DSLRs, making the T7i probably one of the best prosumer DSLRs to buy.
