I would like to hire contractors to work on projects and use your project manager, and also give them access to trouble tickets so I can have people monitor projects at all times.
However I do not want the support personnel to see the payments or billings for the company or the individual clients. Right now you can't show the projects in the support person's dashboard without showing the income.
Income figures should only be visible to the owners/master administrators/Billing and Accounting. Not to everybody.
To achieve this, remove the "Main Homepage" permission from the user's administrator role, and tick the "Support Center Overview" permission.
Now upon login they'll see the Support Overview page (/admin/supportcenter.php) which contains no income figures.
