Current Behavior (if any)
There is no way to import your Steam library into a specific category automatically (it just goes into the Default Category) on the IsThereAnyDeal options page:
chrome-extension://dnhpnfgdlenaccegplpojghhmaamnnfp/html/options.html#itad
Desired Behavior
Allow for importing your Steam library into a specific category, just like on the IsThereAnyDeal Profiles page:
https://isthereanydeal.com/settings/profiles
Motivation / Use Case for Changing the Behavior
This would make it easier to import your Steam library into the category you want, without having to manually move games out of the Default Category.
