Being using EE for few years now.
Sometimes I have to build at least 2 languages in a website. That means I will have a lot of custom fields on my publish page.
So I was thinking is there a plug-in that can force a selection of custom fields under a group or a tab. Similar to the tabs date, Options, Trackbacks, Categories, Pings etc. That will organize my custom fields better.
An idea would be to use the matrix extensions out there but the matrix are still very limited space wise.
cheers
