I just uploaded 20240601, which disables the other buttons on the HUD as soon as one is pressed and adds keyboard shortcuts to them. I haven’t been able to fix it for the dialogs, but this might help a bit. Let me know if it’s improvement.
Oops. :x Fixed and reuploaded.
There isn’t a timer on the buttons. I just disable them as soon as they’re fading and reenable them when they’re unfaded. I don’t particularly like it either, but it might be at the limits of what I can do without a bigger rewrite of the event system. If I spend another 40-80 hours on it, I might be able to fix it, but I feel like I should go back to adding content if it is “solved enough”.
