Hi,
what do you think about writing a full-scale config.php editor? There is one already in the admin tooldbox, but how about writing one that would nut just be a text-editor but a more automized form-based one.
It would read the complete file, get the comments above each var, each var name and value and display it in a form? It would dynamically get all the vars and values so it does not matter if someone has additional variables in there...
Is it worth the effort? Does it make sense at all?
