I am working with a package that supports analysis of flow cytometry data where it is necessary to graphically choose data points for further analysis. This is done in a series of "gating operations that are ideally suited to developing as a series of notebook code chunks. Unfortunately, it seems code chunks can not be used modally at present. This leaves me using this part of the code as if it were free text between code chunks.
Feature Request: modal support for locator() and grid.locator() classes of functions.
