The isMobile variable from useSidebar() is destructured but never used. This suggests it was intended to be part of the logic (e.g., to prevent auto-collapse on mobile) but was forgotten. Consider either using this value in the resize logic or removing it if it's not needed.

The shortcuts use Mac-specific symbols (⌘) without cross-platform adaptation. Windows/Linux users see ⌘ K instead of Ctrl K. Consider detecting the platform and showing appropriate symbols (e.g., using navigator.platform or navigator.userAgentData) to improve accessibility and UX for non-Mac users.

The upload methods don't validate file size, type, or content before upload. While server-side validation is essential, client-side checks can prevent unnecessary network traffic and provide better UX. Consider adding optional validation parameters (e.g., maxFileSize, allowedMimeTypes) to the upload options to enable client-side checks when needed.

The queueMicrotask pattern here creates a brief loading flicker on every navigation. Since you set isLoading to true and then immediately schedule it to false in a microtask, the skeleton will flash for less than a frame. Consider either: (1) removing the skeleton if the actual component handles its own loading state, or (2) using a minimum display time (e.g., setTimeout with 200ms) to avoid disorienting flickers. The same issue exists in DashboardView.tsx.

The test assertions are too weak. All tests only check toBeGreaterThan(0) without verifying the actual count based on the props. For example, the test on line 26-31 sets rows={3} columns={2} but only checks that there are at least 3 .border-b elements, not that the skeleton correctly renders 3 rows with 2 columns each. Consider asserting exact counts or at least meaningful ranges to catch rendering bugs.

Both uploadFile and uploadFiles use the same endpoint /api/data/{resource}/upload. The server needs to distinguish between single and multiple file uploads, which is typically done via different field names or endpoints. Verify that the server expects both requests at the same URL and can differentiate between a single file field named 'file' vs. multiple files named 'files'.

The toast position is hardcoded to "bottom-right" in App.tsx (line 350). Consider making this configurable via the ThemeProvider or user preferences, as some users may prefer different positions (top-right, top-center, etc.) based on their workflow or accessibility needs.

The eslint-disable comment may be masking a real issue. The effect uses activeApp (line 130, 136) which is derived from the appName route parameter (line 57), but activeApp is not in the dependency array. If the app changes (e.g., navigating from /apps/crm to /apps/sales), the effect won't re-run because only location.pathname and addRecentItem are dependencies. Consider either adding activeApp to the dependency array or using appName from the location directly inside the effect.

The onProgress callback is defined in the upload options but never invoked. If progress tracking is not needed yet, consider removing this option from the interface to avoid confusion. If it is needed, you should use XMLHttpRequest instead of fetch to support progress events, or document that this callback is not yet implemented.

The keyboard shortcuts listed here (e.g., 'Toggle sidebar' with B, 'Create new record' with N, etc.) appear to be documentation-only — there's no implementation of these shortcuts visible in the codebase. Users who open this dialog will expect these shortcuts to work. Either implement these shortcuts or mark them as "Coming soon" / "Planned" to avoid confusion.
