In the corridor instruction, I feel like it would be beneficial to have the option to "group" instructions by material layer or create custom groups that you can collapse and expand. Grouping by layer might be hard because thee are some instruction that are "associated" with a layer but are not necessarily part of that layer so they would there not have a material assigned to them. I could also see as going as far as to have a sub group for the left and right side of the alignment or for a specific set of instruction of interest such as a swale or sidewalk.
This would be especially useful for conditional instructions and keeping things organized. The corridor template tool is a fantastic tool but it is pretty easy to get lost in position. The second imagine shows a concept of what I am thinking.
