Meshes do not resize automatically when a shape is resized.
Double click on path to divide row/column by two at that point (there is no reverse operation yet). This is quite useful to select nodes hidden by other nodes (as with conical gradients). Single click on path to select end nodes (with Shift, add to selection, with Ctrl, toggle selection). With mesh tool, you can also box-select multiple nodes. Click on node to select or deselect node (with Shift, add/remove from selection). Square: Tensor handles (see below on how to enable/disable). The mesh will be sized to the bounding box of the object (geometric box for fill, visual box for stroke). One can reuse an existing mesh via selecting a mesh from the drop-down menu in the Fill and Stroke dialog when the mesh icon is selected. Choose pre-existing mesh from drop-down menu. If an object does not have a mesh fill, a new default mesh will be created using the stored values from the Mesh-tool tool-bar. Select mesh icon in Fill and Stroke dialog (Fill or Stroke tab). Select beginning number of rows and columns. Select where the mesh should go (fill/stroke). enable the hidden feature by adding Alt-M (or any other available) shortcut to inkscape/keys/default.xml (Preferences->Interface->Keyboard Shortcuts, search for 'mesh', add, save, replace old file with saved file).
build compiled with CPPFLAGS="-DWITH_MESH" or. This feature is available by default from Inkscape 0.92 on.
