 ## Settings
-* `Ignore Redeemed Keys` is a setting added in v0.1.4. When checked, HumbleKeysLibrary will not import keys that have been revealed on the Humble site.
-* `Import Choice Games` is a setting added in v0.1.5. When checked, purchases that are detected as Humble Choice Bundles will have the bundle's individual games added.
-* `Create Tags for Bundle Names` is a setting added in v0.1.5. When an entry not `None` is selected, it will create a tag in the format of `Bundle: [Bundle Name]` (Updated in v0.3.0)
-* `Unredeemable key handling` is a setting added in v0.3.4. Unredeemable virtual orders (either expired and cannot be redeemed or part of a Bundle where all choices have been made) can be tagged as "Key: Unredeemable" or not added to the library. For existing games, if Tag is selected a new tag will replace the existing 'Key: Unredeemed' tag with 'Key: Unredeemable', if Delete is selected the game will be deleted from the library if it cannot be redeemed.
-* `Enable Cache` is a setting added in v0.3.0. When checked, HumbleKeysLibrary will create JSON files for data retrieved from the Humble API in the ExtensionsData directory. If a Cache file exists, the API will not be queried to prevent spamming Humble. This applies to Purchases, Memberships (Humble Monthly) and Orders.
