Unfortunately the first issue you have is out of our scope of work as it is a preference and not an actual issue with the theme.
The second issue has been fixed in the newest version of Thalia. Please follow the steps below to fix the issue:
- Open the link below, and copy the entire code from it:
- Go to Shopify admin of your store
- Click Online Store
- Click the actions dropdown next to your theme and click edit code
- On the left side, search for swatch.liquid which you will find in the snippets folder
- Open swatch.liquid file
- Paste the code which you copied earlier
Swatches will now indicate out of stock items.
Thank you for using Thalia.
