Is your feature request related to a problem? Please describe.

I am trying to annotate a sparse point cloud. The pcd file contains dozens to hundreds of points, but I can hardly see these points on the annotation interface. Is there any way to adjust the size of each point in the display?

Describe the solution you'd like

Is there a way to modify the point size in the point cloud in the graphical interface, similar to the point size adjustment in rviz ?

Describe alternatives you've considered

Is there any way to temporarily circumvent this problem, such modify a setup file .e.g a yaml or somewhere in the code?

Sparse point clouds are almost invisible in the annotation interface

points are too small to recognize within the annotation panel
