I'll fix this for the next release
for now go to the mod settings and disable automatic shortcut generation

this is a startup error, how am i supposed to go to mod settings without loading the mod?

also crashes with picker,

and im trying todo the same thing rn, my guess is disable the conflict somehow

Turns out the reason why these are failing is because some selection-tools are composed of icons - not one icon. For these the shortcut generated will look odd, as the shortcut supports only one sprite - not a selection which are composited.
Fix (0.7.1) coming out soon.

understandable, can probably better reach out to some of the bigger mods like picker to provide official support instead, but for auto gen of random ones, as long as it has a recognizable name next to it, and at least a memorialize icon it should be fine,
also with how many shortcuts this mod adds, can we have a way to increase the max amount of shortcuts that the bar can hold?

Thanks for the request, I'll get picker mod support in the next release.
The auto generated shortcuts are intended to 'fill in' until a request is made for the shortcut to be officially added (with proper icons, etc.)
Unfortunately the shortcut bar and the extended list is out of the scope of modding AFAIK. I would add in a slider to expand it, but I think it's hardcoded in the game. I might experiment with mod-gui to add an 'auxiliary' bar which is separate from the vanilla bar.

0.7.1 released. Should fix the crashing (Although the autogenerated ones which caused the crash will look different in the shortcut due to limitations of the shortcut prototype)

thx :D that was a pretty quick response and patch, initial post only 3 hours ago!

except now there's the problem of too many shortcuts, the tiny button to open the list goes off my screen

Edit: thats with 1920x1080 monitor 100% ui size

Unfortunately the only fix for this is to just disable autogen or the other shortcuts in the mod from the startup option. I can't directly fix this one either as this gui was never intended to handle so many shortcuts.
EDIT: Technically, you could reduce the GUI scale... but I would never sacrifice readability for this.

could you make a non-startup setting per auto-generated shortcut?

This setting has to be in startup because it generates prototypes. I might make a config file to override these settings in the case where it errors.

im not sure whats possible here but this is speculation as i have some previous experience in modding.
in short tho, is it possible to dynamically add and remove shortcuts from the shortcut list

Nope, once it's loaded in at startup it stays there. I don't think there's a way to hide them either, otherwise I would've made it a per-player setting (which would be a lot more convenient)
