Application Shell 23 block design & features
ApplicationShell23 is an issue tracker shell built with Shadcn UI. The sidebar header has a workspace dropdown with settings, invite and log out, plus search and new issue buttons. Inbox (with a count) and My issues sit directly below.
The content groups Workspace links, Favorites and Your teams. Each team is a collapsible item with a coloured initial and nested Issues, Cycles, Projects and Views links, and the teams group has an add action.
The header shows the current team, pill buttons to switch between All issues, Active and Backlog, a keyboard hint for creating issues and a Display button. The main area is a list of skeleton issue rows grouped under status headers with status rings.
On small screens the sidebar closes off-canvas, the view pills hide and issue rows drop their secondary columns.
