- add a checkbox to create node dialog to create the node as sibling as not child (or reverse in the UI) - fix redo - make [-]/[+] also work in the create node dialog - try rendering the background pixmap from tiles and precalc the tiles at widget init - BUG: clicking on current sketch erases all work - probable bug: ending drawing beyond canvas makes undo a dull boy (crash protection in place) - make sketchwidget borders work again (the bg pixmap precalc thing will break it)
