Provide a “Go to node” functionality to enter a node number and jump there, incl. opening related meta node if not open yet.
If nodes are unique in workflows then the node number itself should be sufficient, otherwise allow to enter a path like 3:470:1207:3102:3201.
Our complex workflows have several hundred nodes, using nested meta nodes and still some meta nodes contain several dozen nodes.
It’s impossible to look into every meta node just to find a node in there.
P.S.:
The “Show Node IDs” option is not sticky in 5.4.0 and cannot be enabled as default in the preferences.
Even with this option finding a node is time consuming and annoying.
