In the current Portal 2, drag&drop option, resizing or moving of tasks get synchronized and data set is loaded again.

It would be great, if we have options here. Eg. the changes are not synchronized and only shown right away.
Datasets can be big and load for 1 - 5 seconds, if a lot of resizing happens, this is noticeable to the enduser. I could see more than one solution:
- add option to synchronize changes instantly (todays functionality)
- add option to trigger all changes
- synchronize the changes in the background (similar to offline functionality). This would only visually show the changes in the front end and not reload the data set, but working on the changes in the background.
