Well, actually it should be a option to stop loading of anything that is already set up in a HDA.
Let's say you have a "node" that has data added already, and is then loading - updating/reading when selecting it. Then it would be really nice to be able to stop that operation with a hard cancel if possible. If houdini had it's own active operation cache file, then by selecting a node and clicking a update option it would continue from were it was aborter would be gold
Or even just start over if so, but at least beeing able to cancel/abort a operation that in some cases can take 5-10min would really be helpful.
But also to have a option to disable auto update/recook/rebuild would be super helpful to. Because i feel that it takes way to long when houdini has to reload the data that was added/imported to a node each time you select it. At least it feels like it is verifying the data and regenerate/realoads the data from scratch, and it take to much time to wait for it to regenerate/reload from the actual tools you are using. But that is talk for later...
