862-873: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick winPersist the threshold when the slider drag ends.

In `@aurora-main/lib/dolphin/pad/pad.cpp`:
- Around line 965-968: Update the trigger override condition in the controller
status handling block so it excludes the NSO GameCube pad identified by the same
Nintendo Switch Pro type and product ID 0x2073 predicate used by
default_dead_zones. Preserve digital trigger emulation for other non-GameCube
controllers while retaining the analog tl/tr values for this pad.
In `@runtime/src/settings_overlay.cpp`:
- Line 512: Update the rebind flow around BeginPopupModal and CompleteRebind so
closing the modal cancels the active capture and clears g_rebind.active,
restoring input blocking and the F10 toggle. Ensure Escape is treated as
cancellation for every RebindKind, including controller captures, rather than
being consumed only by ImGui.

Included review availability: Your plan provides up to 8 included reviews per hour; 7 remain after this review.
- Preserved NSO GameCube analog triggers. - Made modal closure and Escape cancel every rebind kind. - Deduced the native button array size; <array> already existed. - Centralized axis/sign decoding. - Kept threshold updates live, saving only when editing ends.
Thank you so much for your work! Built and tested on Windows, controls work wonderfully. A few UX and rebinding notes from testing:
My keybindings:

I'm assuming unbinding will be possible soon |

For anyone looking to test or play with keyboard & mouse right now while upstream focuses on core stability: I've published precompiled Windows binaries based on this PR, along with a patched Wheel Wizard build that handles installation automatically. |
Brings in the keyboard/mouse rebinding overhaul (patchzyy#162), the Kamek skip-return hook fixes (patchzyy#182, patchzyy#218), the exit button and controller LED fix (patchzyy#221), the autohide-cursor and mute hotkey fix (patchzyy#211), the Linux --sysroot plumbing (patchzyy#224) and the switch to the theofficialgman dawn-build fork (patchzyy#215). Conflicts resolved to keep the VR integration intact: - settings_overlay.cpp/.h: kept both new declarations. The controller rebinding UI takes upstream's click-to-rebind widgets wholesale - our only edit there was wrapping the combo width in Scaled(), and upstream's bindingWidth is already font-relative, so the headset panel still scales. Kept our DrawResolutionMenu() extraction (the VR panel reuses it) while adopting upstream's DrawExitPrompt() and its new DrawTopBar() prologue; kept our Diagnostics menu alongside upstream's exit-button width math. HandleEvents merges both keyboard paths, with the VR recenter hotkey now guarded by !g_rebind.active so it cannot fire while a binding is being captured. - AuroraDawnProvider.cmake: dropped our now-dead Android hash block. Upstream restructured the pins into an if/elseif chain that already covers android/aarch64, with the digest for the new dawn-build fork; our leftover block was unreachable and carried the old encounter digest. - Version plumbing (Build-Installer.ps1, Setup.Windows Program.cs and csproj): kept this fork's own line, which is 0.2.39 and centralised in Launcher/Directory.Build.props, rather than regressing to upstream's hardcoded 0.2.32. Verified: translator 654/654; runtime ctest 14/14 including every VR test; WiiCompiled and RetroRewind link; aurora gx_fifo_tests 262/263, the one failure being the TevRegisterLiveness case already documented as pre-existing on this branch.
