I just ran into unexpected behavior while editing a polygon shapefile in QGIS 2.8.2.
Then I cut that polygon into two seperate poygons:
Then I use the Node Tool to move a vertex:
And that's my question. Why would this create a gap? This means that the Cut tool creates two edges, which is definitely not how it should be, as edges should always be shared, hence reducing the complexity of the dataset.
I have tried to select both vertices, but that does not work; only the one on top can be selected.
Is my only option to activate snapping and move both vertices individually or is there a tool or plugin that can do this?
