Ishtar

• There is no boolean type in the admin for the JSON fields, there is only "choice" which is also for typos fields (with list of choices).

• On the record form, there is no check box (consequence of the previous point)

• On the presentation sheet, false and true are not translated into yes/no oui/non.

By the way, for all boolean fields (i.e. also for Ishtar fields), it could be better to have a check sign or something like that on presentation sheets.
