[xwiki-devs] [Proposal] Add Sandbox in the app bar + Remove Quick Links Panel + Add Tip Panel

Hi devs, I’d like to go on with https://jira.xwiki.org/browse/XWIKI-8919 (which incidentally is a solution for https://jira.xwiki.org/browse/XWIKI-8917 and in general brings consistency). This proposal is about: * Adding Sandbox in the app bar: https://jira.xwiki.org/browse/XWIKI-8919 * Removing Sandbox from the Quick Links Panel and thus the Quick Links Panel which becomes empty by default * Adding a new Tip panel instead to not loose the CTRL+G tip (which was not very well placed in the Quick Links panel) + take the opportunity to add a few more tips: https://jira.xwiki.org/browse/XWIKI-13270 WDYT? Thanks -Vincent
