Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
More check for remvoing scene and scene group. - Without this check, it can make Inkscape crashed if we remove a node that had been removed. - Check whether it owns a parent node before removing. - A removed node has no parent node.
