Hello, I'm glad to show you my application, which makes content installation easy, the only thing you have to do, just download the app, mark what you want to install, and the application will automaticly download these contents and bring it to your garry's mod addons folder, I think everone from the server know how to deal with missing textures, but it could help you bring some sweaters, that's hard to explain how to install addons for sweater. The project is open source and non profit.

Binary (only for windows atm): http://bit.ly/2tZhq4i
In future I can make osx and linux build, because libs which I used let me build for actually all platforms
How does it looks like?:
