==== Motivation
The current block form is confusing in terms of which options are //partial// and which ones are not. It is unclear which options apply only when "Partial" block editing is selected and which ones apply when "Sitewide" block editing is selected. The software understanding also differs from the user mental model. To mitigate this we want to make it more explicit which specific action blocks relate to which action blocks.
==== Proposed solution
|Current UI|New UI - Sitewide blocks|New UI - Partial blocks|
|{F34409458, width=300}|{F34408768, width=300} | {F34408770,width=200}|
* The //Editing// checkbox is replaced with radio buttons for //Sitewide// and //Partial//
* **For //Sitewide// blocks:**
** Show sub-text: //Sitewide blocks include default actions like moving pages, sending thanks, uploading files etc.//
** Show checkboxes for //Account creation//, //Sending email// and //Editing their own talk page//. These options behave the same way as they do currently (//Account creation// is auto-checked).
** All block actions appear indented from the //Sitewide// radio button, per the mocks.
** Sitewide radio button is selected by default.
* **For //Partial// blocks:**
** Until the //Partial// option is selected, no partial block options are shown (including the Pages and Namespace widgets).
** When user selects the //Partial// radio button - show Pages and Namespaces widgets and relevant specific partial blocks.
** Note that //Account creation//, //Sending email// and //Editing their own talk page// options are duplicated here - they work the same way as they work now, with all the same defaults for Partial blocks.
** All block actions appear indented from the //Partial// radio button, per the mocks.
