I am used to digitizing stuff using JOSM, the Java OpenStreetMap editor. Recently, I tried some digitizing in QGIS and it felt rather clumsy.
What I was missing specifically was an equivalent to the "w"-tool in JOSM ("improve way accuracy, https://josm.openstreetmap.de/wiki/Help/Action/ImproveWayAccuracy), which lets you add and move nodes in linestrings/polygons with single clicks. In my QGIS (3.4) to add nodes to a polygon I needed to click on the cross between two existing nodes and then on the place where I wanted the new node to be. The JOSM tool would have allowed me to ctrl-click to add new nodes. This saves one click and mouse movement per new node.
Are there plugins that allow for faster drawing and modification of lines and polygons?
