Description

Having given the Hierarchical clustering a test recently, I encountered a few issues which might need to be fixed:

1. When choosing how to view Excluded elements, choosing dimmed will dim any transactions between clusters, but choosing hidden will not hide any transactions between clusters
   

2. The left and right arrows either side of "x clusters" label seem counter-intuitive as clicking left increases the number of clusters and clicking right decreases the number of clusters. I can see when I click either one that the bar on the hierarchy moves in the same direction as the arrow I clicked but it still feel like something should change. Either the hierarchy should be flipped somehow, or the buttons should maybe be changed to up/down (and moved next to each other)

3. The Shortest Path button was confusing for me as it didn't seem clear what it was going to do upon first glance. Hovering over the button to reveal the tooltip helped somewhat but maybe some additional explanation on the help page could be good

Steps to Reproduce

1. Open new graph
2. Experimental -> Build Graph -> Small World Graph Builder (I changed the number of nodes to 50 but left other parameters as default)
3. Tools -> Cluster -> Hierarchical, play around with the panel

Expected behaviour: Transactions between clusters are hidden when hidden is selected, other features feel intuitive to use

Actual behaviour: Transactions between clusters are visible when hidden is selected, other features either feel unintuitive or counterintuitive

Reproduces how often: 100%
