Areas of GUI improvement before v2.0.0-alpha

[qin-yu]

Here I summarise and expand discussions with @akreshuk and @lorenzocerrone.

In general, the user interface should have sequential layout and minimal options. Here are some details:

Logic Fix

• Hide watershed result once clustering result is added to the viewer
• Remove Scribble layers from proofreading init
• Update proofreading image selections

Formal Fix

• After prediction it should be proofreading (-> finetuning) -> extra
• Improve widget labels and make the case consistent
  • "Pick a file" in Data
  • "Run clustering" to "Run segmentation" in Main
  • "Pmap/Image" to "Boundary image" everywhere
  • "Save state" to "Save current proofreading snapshot"
  • "Stacked: 2D; 3D" to "Mode: 2D watershed; 3D watershed"
  • "Min-size"
  • "Extract correct labels" to "Freeze correct labels"
• change the name of the interface from "napari" to PlantSeg related
• fix "MutexWS" name/val correspondence
  • Need to use Enum in a better way #325

Missing widgets

• Add cropping widget
• Add label processing widgets

New Widgets

• create home/docs widget and fix warnings from Qt Main Window
  • Qt Warning: QMainWindowLayout::count: ? #329
• have a one click solution for nuclei to avoid going back and forth

Widget Refactors

• Show image dimension before letting users choose between, say, "ZYX" or "CZYX"
• Remove "Lifted Multicut" if we have nuclei-assisted fix or move to aggl. widget
• Move "Add custom model" to prediction widget
• Move tabs to top (not so Napary)

After discussion with @lorenzocerrone.

Don't forget to:

• Add cropping widget
• Add remove the biggest instance widget

Maybe we could:

• have a one click solution for nuclei to avoid going back and forth
