I need a simple admin page (ie CMS section) for a site-wide setting (in my case: website's footer content). In SS 3.x I was comfortable using this mod: https://github.com/littlegiant/silverstripe-singleobjectadmin . However it seems to rely on deprecated methods and classes rendering it incompatible with SS 4.
Now I'm looking for a solution and need some advice. Would it be an idea to simply fork silverstripe-siteconfig and tweak the code a bit or does would that be too much of a hassle for the desired goal?
