Keyboard shortcuts; mouse+keyboard equivalence and bulk edit (see details)
1) Keyboard shortcuts: (such as Ctrl-DELETE, instead of 1 right-click + Del-click + confirmation click.
2) Mouse+keyboard equivalence whenever possible: I.e.: ENTER=click
3) Bulk edit (multi-task selection and multi-selections whenever reasonable, backed by recycle bin, buffer reversal= Ctrl-Z, etc.)
4) Copy, Cut & Paste whenever safe (or allowing user settings transferring the "liability" to us)
Without a faster desktop app and similar productivity improvements, it's not ONLY crazy, it's virtually impossible to deal even with hundreds of tasks, which is just fraction of the real need for most of us.
