First of all, I would like to thank all of you who downloaded and tested the app in the last weeks. Your feedback has been very helpful in shaping the future of slashB and ultimately in giving you a useful tool. I really appreciate it!

In the last few weeks, I released three new versions of slashB: 1.1, 1.2, and 1.3. These releases bring a good number of new features, all giving you a better experience in developing and testing websites. These updates are the result of your precious help.

So, what’s new in slashB?

Sync actions

When interacting with one viewport, slashB will mirror all your actions on the others. Click, focus, scroll, forms input: everything is in sync among devices!

Actions are synchronized between viewports

Re-designed devices toolbar

Devices have a re-designed toolbar that shows the device name and a menu with actions.

The new device menu

Some of the actions include:

  • Reloading a device’s page, with the option to reload while ignoring the cache (force-reload)
  • Taking a page screenshot
  • Clearing cache, cookies and local storage for individual devices
  • Opening the Dev Tools
  • Rotating a device
  • Editing a device’s properties

Keyboard shortcuts

You can now interact with slashB using your keyboard. Most of the keyboard shortcuts you would use on any other browser are available in slashB as well. To view all the available shortcuts, open the Help > Keyboard Shortcuts menu.

Zoom devices

It is now possible to zoom the devices and make them bigger or smaller with a single click. Useful if you are working on a small screen or want to have a full overview of all the devices.

More default size presets

There is now a total of 60 default size presets to choose from. It is now easier to test your websites on the most common device sizes, including phones, tablets and desktop screens.

You can also filter the presets to quickly find the one you are looking for, by searching them by name, width, or height.
