Second Gear’s Elements for iPhone and iPad has been updated to version 1.5 today, a major revision of the popular Dropbox-based text editor that adds lot of new (and much requested) features together with a plethora of bug fixes. We previously covered Elements here and here.

First off, Elements now supports sub-folders and Markdown previews. Sub-folders are really a huge deal for many users out there, as now you’ll be able to hook Elements up with other Dropbox-based apps that organize their documents with a similar structure, such as Plaintext. The family of Dropbox text editors keeps on getting more connected and better integrated.

For me, however, the really huge deal is the improved Markdown support: the app can now view Markdown formatted files (.md, .markdown, .mdown, .mdwn) and open Markdown files from external applications that support the “Open in…” feature. Similarly to Second Gear’s own MarkdownMail, Elements can now generate a live HTML preview of Markdown formatted text for you to instantly check on.

Bug fixes and overall performance improvements aside, the app should be working fine on iOS 4.2 now and the file saving system has been completely rewritten. Changes are now saved locally every 5 seconds (so you won’t miss anything), and uploaded to Dropbox when the keyboard is dismissed, you put the app in the background or refresh the file list.

Elements is available at $4.99 in the App Store, and in my opinion is the best Dropbox-based text editor currently available on iOS. The fast release cycle proves that Second Gear really cares about the app, and I’m looking forward to future features and improvements.

Check out the full 1.5 changelog below.
