Don't know whether it is already in the new upgrade, but an Image Preview and a Search Bar in File Manager would shorten the amount of searchtime. Especially when you have to find a productphoto, because the naming for the prodcutpictures is not SEO friendly..
[SANA PRODUCT] We are currently working on improving our Sana Admin CMS editor. We call this project the “Visual Designer” where it will be much easier to create content. In addition, we will also review the rest of our Sana Admin with our UX experts. The file manager is definitely one of the candidates that needs improvement. Thank you for the feedback!
