Lataa Polypane 31.0.0

**Polypane 31**
This release has a new canvas layout that lets you freely arrange panes on an infinite canvas. The elements panel now lets you filter styles, search the DOM tree, quickly navigate to and back from custom property definitions, and a new flex item explainer that can tell you exactly how flex items are sized and positioned.

Polypane 31 also has device presets for the latest iPhone devices, and runs on Chromium 155. [full release notes](https://polypane.app/blog/polypane-31-canvas-layout-elements-panel-improvements-and-chromium-155/)
