I realize this request is largely insignificant, but it should also be very easy... Would it be possible to compile/make distributable a version of pageant with the custom icon that was designed to match Puttytray (original)?
I've never actually seen any original version of PuTTYTray's pageant. Are you referring to the British-police-hat-with-wire icon, as labelled "pageant.ico" in https://b.goeswhere.com/putty-icons.png ?
Did it change the tray icon, too, or do you want that left as the old-style "pageants.ico"?
(I've been looking for an excuse to start working on pageant.)
gh-34: new pageant icon
I can't find an SVG or 256x256 version of the hat icon, unfortunately, which means there's no 256x256 version of the icon, unlike the PuTTY.exe one.
