Splitting cells:

• choose from three options: 1) kmeans on the voxel coordinates, 2) watershed based on image intensities, 3) watershed based on distance transform)
• split multiple cells simultaneously, by selecting multiple cells and click "split"

Adding Spherical Cell:

• in situations where the segmentation doesn't matter, but for the sake of a tracking solution, you can add a spherical cell.
• choose the radius in the UI, for the cell to be added
• the cell will be added where the user clicks. In 2D, this is trivial. In 3D, ray-tracing will find the brightest pixel in the nuclear channel and place the cell there

Double-Click Track Continuations:

• when adding cells (either Instanseg or Spherical cells), you can double-click to create a continuous track.
• single click: adds a cell (as it normally does)
• double click: adds cell + move to next frame + the next added cell will automatically be connected to the previous cell in the same track

Overlapping Cells:

• when adding cells (either Instanseg or Spherical cells), they will never overlap with existing cells. The cells is created, but any pixels already part of other cells are not included. This to prevent overlapping cells, which are currently hard to resolve.

Bug Fixes:

• solved bug where TrackEdit crashes when the parent root cell is deleted
• fixed viewer centering logic when clicking on cells in 2D mode
