[Qgis-user] vector editing

Which version of QGIS are you using? As of 1.2 (I think), there are
undo options for editing...

> 2) are there any trace tools in qgis?
Do you mean digitizing tools? Most definitely! Have you looked at the
editing toolbar/functions? To start, right click on a layer and select
'toggle editing'

Not sure I get what you mean here? After deleting a feature while
editing, does it remain on the map canvas?
