Navigating blocks

Hi, I don't know if I am missing something but after a rather sore finger from mouse scrolling up and down (and up and down ......) my seemingly endless blocks I came across an idea to intentionally place an error block outside the start of various procedures clicks etc throughout the blocks.
Now to jump (goto) to a different block I just use the find error spinner workspace control at the bottom left.
I think it would be useful to have some standard navigation system for the blocks maybe based on this idea another spinner or list with the name of procedures etc. by the side of the warnining and fault spinners (or maybe there is but I still can't see it and maybe you all use this system anyway if so please excuse me)


You could use
