Footprint in taskbar, version 10.0.1

In version 9, I could disable the DOpus footprint on the taskbar: Preferences>Listers>Options> Show lister "footprint" on Windows task bar. Where has this option gone to in version 10?

It's gone, sorry.

Is it gone by design or has is just been overlooked? If the former, I would be very disappointed (in addition to being hard-pressed to understand the rationale); if the latter, can I expect its restoration in some future update?

It's gone by design. There were some issues with it and we didn't feel enough people used it to justify continued support (development and most of all testing) of it, especially in light of changes to the taskbar in Windows 7.

That takes care of the rationale, but not the disappointment. Thank you for your quick (immediate, actually) replies.
