I can / will.
but can you give a list of things you want to be able to modify?
As currently it would be more of a global feature request which would practically need to redesign the entire system to make all pages editable.
While if we make it more specific (like custom mail ports) list it will most likely be picked up much more quick.

Hello,
Basically we want a text area where we can add information for clients. It's best to have areas in the following sections:
Domains
Default.aspx?pid=SpaceDomains
Web Sites
Default.aspx?pid=SpaceWebSites
FTP Accounts
Default.aspx?pid=SpaceFtpAccounts
Mail Accounts
Default.aspx?pid=SpaceMailAccounts
Databases - there are couple of providers here, so I'm not sure if it can be done for all or if we should do it individually
Default.aspx?pid=SpaceMsSql2005
Default.aspx?pid=SpaceMsSql2008
Default.aspx?pid=SpaceMsSql2012
Default.aspx?pid=SpaceMsSql2014
Default.aspx?pid=SpaceMsSql2016
Default.aspx?pid=SpaceMySql5
File Manager
Default.aspx?pid=SpaceFileManager
Web Applications Gallery
Default.aspx?pid=SpaceWebApplicationsGallery
Scheduled Tasks
Default.aspx?pid=SpaceScheduledTasks
Thank you,
Chris
