[[IDEA]]: t-SNE plot options

[covingto]

Single Cell version

Orange version

Expected behavior

I would like to be able to color the points on the t-SNE plot by gene expression. This would allow me to select clusters of cells by supposed cell type.

I would also like to be able to make polygon and multiple selections from the plot.

These features would allow me to better use the differential expression tools so that I can look for differences in expression between more defined subgroups of cells.
