PHP Script/Plugin Customization (Veno File Manager)

[login to view URL] i have a license for the plugin. i can sent you a copy to look into the code this is what i need have be added/adjusted: 1-the layout stays like it is, and the new pages are added in the horizontal navigation in the top. In the mobile version or when the browser frame has low width, like 300px, then the 3-stripes button needs to be clicked to open the navigation bar, so the new pages should also be shown in there 2-the main page that shows users private folders should have some graphics below the folders that i will later determine 3-the first new page is a direct link to the open folder that every user has access to, but can only download files from, and below there are also graphics 4-the second new page is a page with a FAQ-Box, a Ticket-Box that can be answered by the admin OR a form for sending mails to the admin's mail adress, and some additional graphics 5-all Links to the official plugin should be deleted 6-a page that is accesable by clicking on the footer, with a text giving legal information. It is not linked in the navigation bar 7-When clicking on the files, Diagrams (.svg), Spreadsheets like Google Sheets or Excel (.XLS, XLSM, or .GSHEET), Text Files (.txt) and PDFs (.pdf) the files should open in a frame in which the user can edit and view the files 8-the admin has to confirm every user that is trying to register, before the confirmation by the admin the user cannot login 9-also afterwards you should clear some minor bugs or if something doesn't work on my server, but we can make a separate gig for that
