Looking for a mod or add-on that improves snapping

[Ikorolch]

Just looking for a general mod or add-on that improves essentially how you put parts together in the VAB, such as improved snap, alignment, vertical snap, etc. Sometimes it just get's extremely frustrating, and close to impossible to put several things together i.e. when there are two radial decouplers and your trying to mount another fuel tank. I've looked all over the forums but I cannot find anything like this. This something like this exist? If so please point me in the correct direction. Thank You.
