We run about 10 different themes. This one looked great but i would not recommend it any more. There are many unresolved problems (page loading time, no animated sections like videos etc., no real updates just a view bugfixes in 2 years). It seems that the priority of this company is more maintaining its bigger themes and developing new themes and apps then really caring about this theme here.

Hey Upstitch team, thank you for your review. We actually just released a major Cornerstone update today which addresses some of these critiques directly (check out the new video sections for example). If you have any outstanding concerns, please email us at help@fluorescent.co and our support team will be happy to guide you and take any additional feedback that you have about future development.

Version 2.0.1 February 14, 2025

Cornerstone v2.0.1

Fixes and other improvements

  • Fixed the search result dropdown being cut off

Version 2.0.0 February 11, 2025

Cornerstone v2.0.0 adds some new video-related sections, expands header options related to search, and fixes some minor bugs.

Added

  • A "Video with content" section.
  • A "Video with content split" section.
  • A new option to choose mobile-specific videos for the "Video hero" section.

Changed

  • Important: Updated "Header" section settings related to search.
    • Originally, there was a "Search bar" section of the settings where you could choose to enable/disable the search bar, as well as choose the appearance of the search display on mobile. With this, the search bar enable didn't apply to the icon appearance on mobile.
    • We've updated things so that there's a "Search" section of the settings with an enable/disable for search as whole, and then added a desktop-specific appearance setting, so now you can choose the appearance on desktop and mobile independently while maintaining the ability to enable/disable search showing in the header.
    • Due to this update, you'll need to go to the "Search" section of the "Header" settings and ensure that settings are configured to your liking.
  • The "Desktop layout" setting in the "Header" section has a new option of "Logo left, search right". This is mainly intended for the case that the "Desktop search appearance" is "Search icon".

Fixes and improvements

  • Fixed product page only adding a quantity of 1 to the cart when more than 1 has been selected and there are complementary products in the left column.
  • Fixed the header cart label reverting to English when the cart is updated and a different language is selected.
  • Fixed the slideshow not working when it's not full-width.
  • Fixed the Shopify subscriptions widget not displaying radio buttons correctly.

Version 1.3.4 December 17, 2024

Cornerstone v1.3.4 fixes some high-impact bugs, and makes preparations for the upcoming font deprecations.

Changed

  • Updated preset fonts to account for recent deprecated fonts.

Fixes and improvements

  • Fixed an issue where the "Show more" button in the Storefront filters sidebar doesn't expand the filter list.
  • Fixed an issue where the Sticky add to cart bar's price was not updated as variants were selected.
