I stuck this in as an aside on a thread of Cyphyr's earlier this week, but I thought I'd mention it again here.
One feature I'd really, really like to see added would be a 'Lock' feature in the node view. It could work on either a group-by group basis, or for the whole project at once. The idea would be to prevent you from accidentally disconnectinng connections. (Not that it's ever happened to me...
).
Another nice addition would be a 'Minimize' feature for node groups. I mentioned this as an aside when the idea for additional boolean operators was under discussion. It'd make dealing with complex node networks a LOT easier.
So those are my additions to the wish list for this, the week of 14/09/07.
