Recently the Histogram Plot command was improved. Support of float images
is one of the enhancements in place.

IJ2 keeps all selections (and auto populates the Overlay Manager) by
design. The issue of context menus for overlays (including delete) is known
and will be addressed. See: http://trac.imagej.net/ticket/1084


> Selecting an image by clicking into it (while a selection tool is active
> in the toolbar) should not create a new Roi (maybe unless the user drags to
> extend the roi).  Even worse, clicking on the white space below an image
> (if the window is larger than the image, such as for the 'Blobs' sample,
> see also ticket #1060) currently also creates a new Roi.

> Creating a selection on an image shown at a zoom level different from 100%
