hello guys
first question:
i want to hide/remove some fields(estimate, remaining,....) and add some new fields to the specific section that i want
i mean the screen that appears to the right when you clicked on the issue (first pic)
and of course i do not want to change the configuration of fields(in hiding cases)

second question:
and the same actions of above when you double click on a issue (second pic)

and i want to show or hide fields in these two screans (first an second pic of above) based on the project role that you have.
thanks.
