XML workflow import/export; initial dataset object export; multithreading support for app workers
Multi-threading in workflow - Individual apps can now run their processing in a separate thread and return control to the UI
- Threading implemented in a number of plugins with largest wait time
- Loading of workflows now doesn't auto-load data; speeds up and prevents pointless churning
- Needs implementation of hierarchical blocking (1->2->1 should allow multithreading on 2, but block 1 til both inputs ready)
