I know all the 1.8 this and that ended, but I just came up with an idea so good that it would solve one of the most major problems for builders.

In-Game Connection Points Manipulation

Basically, in game it's already easy to connect something to another part, you just use either CTRL+K or your mouse to drag the object. But sometimes a part can accidentally connect to multiple parts at once when you don't want it to. This makes you have to go through the whole fixing process and it's a waste of time and motivation.

My suggestion for 1.8 is to make an easy to access menu tool that when selected, makes your entire build transparent (not invisible), and then a little square pops up at every place where 2 or more parts are connected. From here you can either draw a new connection point (By selecting "Make Connection", then highlighting multiple parts that are touching which you want to connect, then clicking OK, making the new connection points solid) or you can remove a connection point (By selecting "Remove Connection Point", then clicking on all the little connection squares, making them change in either color or opacity. You can select the squares again to save them in case you made an error.). After you finish, you can go back to the Connection Point menu and click "Save", which makes all changes official, so the only way to revert them is to click the glitchy "Undo" button on the bottom corner of the screen. Through the Connection Points menu, you can also select a connection point and change it's strength, so that parts are not sliding against each other when you don't want them to.

Why do we need this? Many players have connection point issues, especially when making more complex builds which require many internal rotators and pistons, etc. The connections on the rotator-based mechanism people make can accidentally clip into other parts, making the mechanisms unusable. By removing unwanted connections, it becomes much easier to fix these game errors and builds will be coming faster, and more builders will come up to this game which some people consider "dying".

I hope somebody implements this, it would be really helpful and important for the growth of the game.
