Centralize native palettes, presets, typography, controls, menus, calendar rendering, and icon assets in ferese-theme. Reuse the shared components across the shell, settings, lock screen, authentication prompt, and screen-sharing chooser.
Attach themed dialogs to compositor-owned materials, correct backdrop capture and sampling across output transforms, smooth patterned backgrounds, and prevent clipped picker buttons with the configured shell font.
The hidden-window sweep built a Vec of cloned Window handles purely to
work around the borrow checker: unmap_elem needs &mut self.space while
the iteration borrows self.window_ids. Move the space out with
mem::take instead and unmap in place, dropping the allocation and the
per-window clone.
Behaviour is unchanged. unmap_elem only removes the element passed to
it, so it cannot affect element_location for any other window, which
makes checking each window immediately before its own unmap equivalent
to testing every hidden window up front; the unmap order is the same
window_ids iteration order. The |= is deliberate so the check never
short-circuits past an unmap.
This is a cleanup, not a measured win. The sweep is dominated by the
linear scans inside element_location and unmap_elem, and a Vec only
allocated when windows were actually hidden, so the saving is small.
Verified with twelve live foot windows across forty workspace switches.
visual_scale_for_window returns 1.0 whenever Overview is not
presenting, so gate the window_under_visual walk behind
is_presenting() and read the scale straight from the constant.
Use hash_map::Entry for the window geometry insert so client_size is
only computed on the vacant path, and reuse the elapsed time already
sampled for the frame in expire_wait and presentation_size_request
instead of calling start_time.elapsed() a second time.
Split ScrollingLayout validation so the per-frame geometry solve only
checks scalars and keeps the full tree validation behind debug_assert,
removing a HashSet build from every frame. Replace the per-region Vec
in decode_regions with a stack array via as_chunks, and skip the window
hit test in PointerMotion when Overview is not presenting, where
visual_scale_for_window returns 1.0 regardless.
Guard sync_window_stacking behind a check that the space already matches
the target order with uniform z_index, avoiding an O(n^2) raise_element
loop on every redraw. Narrow window_under_visual to the space iterator
outside Overview, keeping the collected and sorted candidate list for
the Overview branch where front-to-back order is load-bearing.
Raise rust-version to 1.98 and clear the resulting Clippy findings
across the workspace: let-chain collapses, clamp, and while-let loops.
Keep notification actions and dismiss controls visible, compact and animate history, and add themed icon controls and grouping.
Include notification settings, session integration and documentation, on-demand workspaces, and performance baseline notes.
