Polypane 3.1 is now available and with over 30 new and improved features it's our biggest release ever.
With Polypane 3.1 we're introducing the Polypane elements panel: A completely new elements panel written for Polypane that syncs between all panes letting you easily update styles, content and attributes.
But with 32 other new and improved features there's way more to explore. There are 2 other new panels: Storage and Outline. There's an updated Meta panel that highlights issues, a new Discord preview and updated Twitter and Facebook previews. We've added the ability to import and export workspaces and added some default workspaces for convenience. There's new overlays, updated existing ones and improved performance all around.
Polypane element inspector
In Polypane you've had access to the Chromium devtools element inspector and while it works fine it was never developed to support multiple panes.
So we built our own:
The Polypane element inspector is extremely fast and makes common tasks really easy. All synced with all panes, of course. Here's a quick video showing it in action:
The element inspector is filled with smart features and it s a joy to use. Listing all the features would make this announcement twice as long. Very quickly: select elements in all panes at the same time, live editing of content and attributes, custom widgets for styling, one-click copying of CSS rule sets, automatic contrast checking and so much more. For a full rundown, read the documentation
Meta panel updates
One important theme in Polypane is that we want to help you create better sites. That's why we added warnings for common issues in the Meta panel. We show warnings for missing but important meta elements or when your title and description are too long or short.
If you define certain meta values more than once, we'll show you a warning indicator for that too. Other new things are more prominent place for the canonical url, all icons are now downloadable and if your page supplies oEmbed information that information is now also shown.
Social media previews
All social media cards now have a background color that matches their websites for both dark and light mode, so the preview is even more accurate and you get a better idea of the context where your card is shown.
We added a new social media preview: Discord, in dark and light mode. One of the cool things in the Discord share card is that is uses your site's theme color for the border.
Since the last release of Polypane, Facebook updated it's design and added a dark mode, so that is now updated in Polypane. New (or rather, back again) in this design is that Facebook will show a part of your og:description again but only if your title fits on a single line.
Other new panels
We also added two new panels: Storage and Outline.
The Outline panel shows an outline of your headings according to the HTML5 outline algorithm. Easy to quickly check if your page has a logical heading structure or if you're missing steps or have sections that need a title but don't have one.
Workspace import and export
We heard from many of you that you wanted to share your workspaces with your colleagues, so we've added the ability to export and import workspaces. Export your favorite workspaces to Polypane workspace files, share them with your team and they can import them into their own workspaces.
We've also added a new tab with default workspaces. They include our default three-pane layout, the device lab, all our iOS devices, all our Android devices (including a new Moto G4 preset), the 6 most common screen sizes used worldwide and the default breakpoint for Bootstrap, Material UI, Tailwind and Bulma.
We added a new overlay, Hostile CSS. Hostile CSS will inject styling for all default elements. You can use it to check if your component styles are properly isolated from any default CSS.
Color overlay now suggests alternatives
Like our free online Color contrast checker, the Contrast checker overlay will suggest improved colors that have enough contrast. This makes fixing your colors really easy.
Set your own tab homepage
When you open a new tab we show the default 3 panes and the getting started page. in 3.1 you can now change this 'homepage' to whatever configuration you want. Arrange your tabs the way you like, pick a URL, then set the homepage to your current view from the main menu.
