Given even a small set of plugins, and given the few available keyboard shortcuts (not already assigned to XD), it would make sense to give any currently-open panel plugin “priority” for any keyboard shortcuts.
The idea is that, when the panel is open, its shortcuts would take priority over (override) any other plugins’ shortcuts.
This would make panel plugins more like “mini-applications” that have their own shortcuts in effect while running, and would make shortcuts useful again.
