A way to test several themes fast?

[rudolfschmidt]

Hi, thanks for your work and your collection.
A question, do you know an efficient way to test through all themes fast?
At the moment my workaround is to select a theme in .Xresources, then execute xrdb .Xresource and open a new instance, to go through your collection (screenshots could be an alternative option) takes a lot of time.

Thanks
Best
