CutMeShort works really well for my purposes: I mainly need in-app links to my YouTube channel, and it works great. It's not an overloaded tool with useless features, and it's easy to use.
Visually, I would like a nicer design. Also, the folder selection is a bit hidden – that could be made easier. Last but not least, I would like to see an app or at least a smartphone-compatible version. The small website thumbnails are displayed as preview images in the link list. However, if you always link to YouTube, this can be confusing. It would be nice if you could store your own preview images here or if the app would pull the preview image from the website as a small image.
But all in all really a nice tool.
