improve plugin GUI
Gmsh Plugins are very powerful but the inerface is quite hard to use. Here are some suggestions to improve it:
- Several plugins have non-intuitive names (Evaluate, Extract, CutMap):
Evaluate -> Modify ou EvaluateInPlace Extract -> Evaluate CutMap -> CutIso or CutLevelSet CutParametric -> CutParametricCurve
-
CutGrid should work for 3D grids (specify 4 points and U,V,W)
-
Divergence, Gradient and Curl should be combined into a single Derivate plugin (like Integrate)
-
There should be a short (one line) help in the main plugin window (so that you don't have to go into the Help tab just to understand what the plugin does)
-
There could be plugin categories (at least "basic" and "advanced"?)
