With a lot of predecessors linking tasks, the gantt view can get crowded and hard to visualize with a lot of additional lines between tasks.
I'd like the ability to toggle on/off the predecessor linking arrows. This was a setting in MS Project that I used quite frequently and miss in Smartsheet.
I agree with a very large project plan it is very hard to share the plan with others / update with all the predecessor lines showing. It looks confusing and would be so much better if these could be removed or even better toggled so people could choose. When using the plan with others who are not so familiar with smartsheet it just puts them off using the tool as they think it looks awful.
