SharePoint Designer 2013 Link is missing

I was trying to open SharePoint Designer 2013 from Site Action (As usually do with SP-2010) but found that this link is no more in SharePoint 2013 site.

I then decided to traverse the master page and found that Menu Item for SharePoint Designer is missing from Seattle.master( This is default master page for SharePoint 2013).

I then made a copy of the master page and Added the following:

<SharePoint:MenuItemTemplate runat="server" id="MenuItem_EditSite"

                                                       Text="<%$Resources:wss,siteactions_editsite%>"

                                                       Description="<%$Resources:wss,siteactions_editsitedescription%>"

                                                       ImageUrl="/_layouts/15/images/SharePointDesigner32.png"

                                                       MenuGroupId="300"

                                                       Sequence="304"

                                                       UseShortId="true"

                                                       ClientOnClickScriptContainingPrefixedUrl="EditInSPD('~site/',true);"

                                                       PermissionsString="AddAndCustomizePages"

                                                       PermissionMode="Any"

                                                />

 And saved the master page. Made this master page default. And now you are able to open the SharePoint designer from Site Actions.

But as we know that when we save the master page it prompt as follows:

Means we are unghosting (Please see Ghosting and Unghosting here if you are not familiar with) our master page.

So, Then I decided to create a custom Action for this. And yes I have done this. Please find solution file here
