Read and Write Property Bag items
It would be great to be able to get SPWeb Property Bag values - and also SET the values within a web.
These are often used to store "about a web" properties - but can only set via code (C#) - or CSOM (JS).
Eg. When we use a Nintex Workflow to create an SPWEB, also add a property such as 'locale' - and then can use that to display an icon on the site home page.
Many other uses - there is a custom action BLOG post about this - but would be good to have within the core product - for READ and WRITE.

Was looking to post this exact request but thought I'd search to see if anyone else had. I also support this request, with the whole indexable web properties now in SP2013 this would open up a ton of awesome possibilities in site provisioning etc
