Thank you, Mr. Dam, for your responsiveness.
1) Ok, I understand, even if it's in the joomla kernel, there's no way to reduce the font size (with CSS)?
2) It's perfect, I missed this option (Access Level Inheritance). It works, thanks again!
3) You missed my question.
I would like to approve documents for certain categories but:
- if in edocman's general config "Require approve new document" ? is No
- in the "Auto Approval" category = "inherit global config" or ="no"the uploaded doc is still publishes 
- in the "Auto Approval" category = "yes" still publishes the uploaded document
- if in edocman's general config "Require approve new document" ? is Yes
- in the category "Auto Approval" = "inherit global config" or ="no" approval of uploaded document is required
- in the category "Auto Approval" = Yes approval is still required
3') Ok, maybe a next new eDocman menu (on the wish list). This is the only function that requires a user to go to the backoffice.
4) I'd like to notify a specific person (a manager) by email when a new document is created in a category... but I can't do it.
I get lost with the general configuration, that of the category, that of the plugin.
ex : someone uploaded a doc in the "computer" folder, the category manager should receive an email
What steps should I take?
Thank you !
