Hi Nari,

If you make a mistake you can simply use Ctrl-Z (Undo) to undo your changes. The immediate editing is not going to be removed because we need it for future changes. Of course, we will keep an eye on performance. It would help us if you could send us a task file (possibly anonymized with Help→Anonymize) and tell us what actions exactly are slow for you. Please use the bug tracker for that.

Thanks, Frank

Won’t be ready for some time though, and I think we’ll need some serious beta-testing before releasing this.

Release 1.1.0 allows tasks to have start and end times.
