The value selector building blocks (cf. https://wiki.mozilla.org/Gaia/Design/BuildingBlocks#Value_Selector) are decentralized across different apps, their main iteration being located in the System app. The following should be moved to shared/style and apps depending on this updated: apps/system/style/value_selector/* apps/system/style/bb/ (which also includes date_picker and time_picker) On a high level search through apps, copies of value_selector.css reside in (Note: this list might be incomplete): apps/bluetooth/style/bb/value_selector.css apps/email/style/value_selector.css ** apps/system/style/bb/value_selector.css ** apps/system/style/value_selector/value_selector.css

It seems that value selector also has some js code in apps/system/js/value_selector/, I suppose this would also need to be moved to shared/

I think the only needed files to be shared are just the .css files. value_selector .js files should be keept in system folder as the .css are officially BUilding Blocks

Have you manually tested all the dialog to see if it works still?

Sure, i've tested all value pickers (time, date and value) manually from calendar app and from ui test app all the confirm/dialogs/pickers available. I don't know if there is other ones to manually test from other applications.
