Polypane 2 is out! In Polypane 2 we're introducing a bunch of often-asked for features, like full device emulation, filtering and a vertical view mode but also some completely new functionality that just might change how you build websites: overlays, simulators and visual diffing.
These new features give you better insights in your site right at your fingertips and make laborious tasks like contrast checking or QA much, much faster.
We decided to give the logo a little refresh. The colors in the previous version were a little dull and no longer fit with the rest of the colors in our design.
The new logo is also more legible in small sizes, feels fresher, and if you squint it kind of looks like a P.
New view modes
We streamlined the view modes in Polypane. There are now four: Horizontal, which is the default view, Vertical, which is new and lets you scroll vertically to see all panes, Focus mode and Full mode. Devtools mode is gone because Devtools extensions can now be used everywhere with our new isolate panes feature (read on for more about that).
Vertical view mode is really nice to get a really high-level overview of your site by zooming all the way out:
All view modes now have single-key shortcuts so switching between them is even faster. Read more about them in the documentation: view modes.
Overlays and simulators
Polypane now supports "Overlays" for each pane. We already had an overlay for all panes with our "layout debugging" feature, but they can now be applied per pane and the available number of overlays has grown to over 15 items.
Simulate all versions of color blindness, quickly test your site for accessibility issues or make your page editable to quickly make text changes. There's a few more overlays, so try them out!
Overlays will help you develop faster, catch bugs earlier, test your site in new ways and in the end, produce better websites.
In the image above from left to right we have: an accessibility check, a colorblindness simulator, a farsightedness simulator and a dyslexia simulator.
Coming in the next version: Overlay plugins
The overlay system is going to be opened up so you can write your own overlays and share them with other Polypane users. Details are still being worked out, but if you have a good idea for a new overlay and what to build it, please reach out and we'll get you in the plugin beta.
Isolate panes (in beta)
Isolate panes is a new mode that changes the way Polypane works. Websites in Polypane up to now had a shared context, which meant that for example we had a single devtools for all panes. With isolate panes, each pane has its own context. With this each pane has access to devtools extensions, and we can do full device emulation.
You can set the device type, emulate touch, configure the pixelRatio and set the user agent. Our Device presets have been updated to include these, so they will automatically be applied in Isolate panes mode.
Custom HTTP headers
A unique new feature in Polypane is the ability to set custom headers per pane.
With custom headers, you can send extra information to your server and test things like multiple languages using the
accept-language header, or come up with your own headers and configure your server to do things like test multiple themes, print additional debug information or discard destructive actions so testing forms becomes much easier. Anything is possible.
Read more about device emulation and custom HTTP headers.
Visual diffing with reference images
Each pane can now have a reference image applied to it. Reference images can be overlaid or shown side-by-side with pane. You can use this to compare a site to it's original design, or compare a site to a screenshot made earlier.
We don't think website should look exactly the same as the design, and they're always going to be cross-browser differences so pixel-perfect matching shouldn't be the goal. But this will significantly speed up the work for anyone doing QA or checking that a design has been implemented correctly, and combining Polypane's screenshot functionality with the visual diffing option in the reference image feature is immensely powerful.
Find out more about reference images.
You can now quickly filter panes based on their device category (Mobile, Tablet, Desktop and Other). If you have a custom list of device presets, it will use your own custom categories. This will quickly let you toggle hide and show various types of devices without losing your custom set panes.
