The suggestion has been noted, as said by 8x, there is already a topic on this. As stated in the 'Reminders on Posting' topic:
Check Older Threads
Scan through recent threads (last 1-2 pages) and see if there's a suggestion similar to what you have in mind. If it is, a good idea is to give input on the other user's suggestion, at the same time throwing out your idea in the thread to add on to the original suggestion. As a reminder, posting in a thread where the last post was more than 2 weeks old is not allowed.
Locking this up, since the suggestion has already been made, please post your views in the topic for that suggestion! :)
