Marlow has received 4 updates in the last 12 months.
This update brings new collection and product page templates, three countdown sections under a new Promotions group, and an Arabic storefront, with a round of fixes to mega menus and the header.
The theme now comes with a fifth preset, prices B2B orders by quantity, docks Shopify's chat into a drawer of its own, mirrors itself for right-to-left languages, speaks 31 languages on the storefront and 21 in the theme editor, with a few fixes along the way.
We've added a new Elvara preset, two new sections, hover zoom and new button controls, and a round of accessibility and bug fixes.
Love how much I can customize with the blocks. I’ve been able to create some sections that I couldn’t do with other themes. Support is also really helpful. Overall, really happy with the theme!
I've built shops with quite a few themes, both premium and budget. The new theme from ModuTheme is truly fantastic. Beautiful design, tons of customization options, and great support on top of that. P.S. The bundle builder is amazing. Thanks!
Really like the block system and custom section. Gives me way more freedom to build my own layouts. Support has been great too. Very happy with Helix so far
