I've deleted Nexus Root icon and all is gone???
When i installed, ive wanted to move unnecessary items to trashcan,
And when i moved this logo, bar is completely gone and i cant get them back or recover.
I've tried uninstalling but not helped.

Any ideas?

Well, the program DID warn you, in no uncertain terms, that dragging the control icon into the trash can would PERMANENTLY delete the dock and ALL its contents!

This is one of the ways to delete docks - the other is to right click on the control icon and select 'delete dock'.

Anyway, although your previous dock is now lost forever, you can quickly create a new - empty - one by right clicking on the left mini-tab of WorkShelf and selecting 'Create New Dock'. You can then add stuff to it via drag & drop or by right-clicking on the edge of each dock tile and selecting 'Insert Item' from the context menu.

Hope this helps,

i cant find 'Create New Dock' >_< show me

EDIT: AA! NOW I GOT IT dident anderstand what you mean by *the left mini-tab* but i found it now ^^
