I don't typically use apps on the tablet. I prefer to use software programs to edit photos and videos. For video I work in Final Cut Pro 7 and for photos I work in Photoshop CS (very old version but does the trick). That's where I work on my thumbnails and cosplay photos. When I do gameplay footage and I just need to make some minor adjustments, it's quicker and easier to use Lightworks on the PC laptop and I create a screenshot with the Windows 10 thing, but then I bring my images downstairs to do my thumbnails in Photoshop.
