More and more I am adding hints and information within the Admin Panel using the editable type message - it is helpful for clients and can deflect queries and help keep the site looking good by encouraging and informing them to do the right thing. Sometimes all these hints look a bit of a mess and take up quite a lot of space. It would be nice if we could have a ? icon over which the client could hover - with a pop-up containing the help text inside!
That is a good suggestion and we had something along the same lines for the next version.
For the time being - couldn't something similar (i.e. text in popup) be done using the 'editable type message' technique by injecting some popup library into the admin-panel?
