+- [ ] BUG: CTRL+SHIFT+CLICK not on a node shows an error; should just do nothing.
 - [ ] Slow changing of socket sets / range on wave constant.
 - [ ] API auth shouldn't show if everything is fine in Cloud Task socket
 - [ ] Cloud task socket loads folders before its node shows, which can be slow (and error prone if offline)
 - [ ] Dispersive fit is slow, which means lag on normal operations that rely on the fit result - fit computation should be integrated into the node, and the output socket should only appear when the fit is available.
