Dear Wayne,
I thank you very much for your updates which are already improving a lot the
ROI Manager tool.
I would just have two comments on these updates:
>> - Macro recorder: the recorder isn't anymore saving the show_all
>> and label fonctions of the ROI Manager
> This regression is fixed in the latest ImageJ daily build (1.49p13).
"roiManager("Show All");" is recorded the first time you press the "Show
All" CheckBox, but after that it is not recorded anymore, as
"roiManager("Show None");" is correctly recorded each time you deselect the
"Show All" CheckBox.
In the same way "roiManager("Show All with labels");" is correctly recorded
as "roiManager("Show All without labels");" isn't recorded each time you
press the "Labels" CheckBox.

Up to now in ImageJ it is possible to simultaneously display all the ROIs in
the ROI Manager with the "Show All" feature together (= simultaneously) with
a selection and a ROI.
Now let's say you have a couple hundred of ROIs within the ROI Manager, and
you want then select several tens of them is order to apply a logical
combination (OR, XOR, AND)...
Today this is a quite difficult task unless of course there is an easy
solution that I may be missing.
What I'm thinking about is a code similar to what is running behind the
"Show All" feature as soon as you select more than a ROI within the ROI
Manager.
Only the first ROI is drawn as up selection, but behind you see all the
other selected ones and this selection is of course as well ignored in the
case the "Show All" CheckBox is set to "true".
I thank you very much in advance for your answer and work on this.
Have a nice day,
Philippe
