hello,

there's no such option out of the box, no...
you want to de-activate for only some specific users?

Yes Germi ...

You know ! - by default, the "edit" & "delete" option show up when you pass the mouse next to the category names .... I wish to have that option turned off ... for certain users .. idealy, only the one responsible for treasury should be able to delete or edit ! - while other members should be able to view without being able to make changes in the sums, transactions or operations shown in the general view ... ! ... I tried to apply ACL settings for various access levels .. but .. no can do ! ... that would be a nice feature to have !

well, actually, there's the main setting on Expense Manager where you can choose "which access levels can add/edit information".. isnt' that enough? I mean, if you set it to a particular user access level, that should be enough.. shouldn't it?
