I love using the YXI installer for distributing custom macros; I have even used to install an entire palette of macros. However, when installing to a new, user-defined palette, I still need to instruct users to copy custom_palette.png into C:\Program Files\Alteryx\bin\RuntimeData\icons\categories.
It would be nifty keen if we could add custom_palette,png into the config.xml file and have the YXI installer place the file into the \icons\categories directory.
I imagine that some checks would need to be added, to ensure we weren't overwriting icons for the built in palettes.
