Can't connect more than 2 spline nodes at a time

[Jake]

The selection order matters. If you have two splines A and B you want to connect to C:

• Select an end CP of A and the target CP of C afterwards (hold CTRL to select both CPs), then click on "Connect"
  
• Select an end CP of B and the tgarget CP of C (can be the same as above), then click on "Connect"
  

Note that the source CPs (the CPs of A and B) needs to be the start or end CPs! Btw, this limitation will go with the next version.
