Godot is a completely free, open-source, cross-platform, and lightweight 2D + 3D game engine. It started as a 2D game engine, but later expanded its capabilities for 3D game development. Compared with many other game engines, it is small in size, rich in features, simpler and easier to use, and more friendly to the novice game makers. The games made with Godot can be simultaneously released to Windows, Mac, Linux, Android, iOS, UWP, and HTML5 platforms.

There's no doubt that YouTube's official online video player solution is seriously behind the times! I can immediately name its two drawbacks: 1) The subtitle box can't be resized, and its position is erratic, especially when it is near the edge of the progress bar and bobs up and down with play/pause; 2) Among Miniplayer, Theater mode, and Full screen, there is still a very useful browser-based fullscreen mode missing. Unfortunately, Google hasn't been in the mood to improve its YouTube player yet.

Sometimes it's necessary to keep track of the computer use for a number of reasons, like a company wants to know how its employees are doing at work, or a parent wants to know how their children are using their computers, and you want to see what others are doing on your computer after you leave. This is where software like the keylogger (keystroke logging) comes in. But you'd better not use it for illegal or unethical purposes!

MagicaCSG (CSG = Constructive Solid Geometry) is a small, simple, and free 3d modeling software, developed by ephtracy (the creator of MagicaVoxel and Aerialod). It's essentially a lightweight signed distance field editor and path tracing renderer with modeling processes like dynamic subdivision surfaces and fast Boolean operations, which makes 3D modeling as simple, easy, fast and free as building blocks.

DeltaWalker (AKA: Deltopia DeltaWalker) is an advanced and professional file and folder visualization comparison and synchronization software for Windows, Mac and Linux platforms. It has a lot of features and is powerful, but it pales in comparison to similar tools like Beyond Compare. Especially since it's written in Java and using the Eclipse IDE, the entire program is too bloated, which is something AppNee can't stand.
