Paywalling basic features like allowing side to side browsing is atrocious. Could be a great application and browser, but unfortunately greed is the name of the game here. It could be the killer app with all the new ones gaining steam like Arc and Sigma, but if it's going to continue to gatekeep basic features, it will fail.
I am the President of a an amazing Digital Agency and I could not survive without the amazing browser. I have tried so many, and this one was super great to organize and make it easy to focus. Love it and highly recommend it. I am a PAID subscriber and will gladly keep paying for these amazing upgrades!
Sidekick has a great browser they've put together. My journey began with Chrome Canary then Franz then Station (RIP). Eventually, I was glad to find and stick with Sidekick as my daily driver. It is the browser I switched to and have advocated for time and time again (I put a link to it in our onboarding manual for my firm). What I appreciate is how it saves me installing 5-10 different Chrome extensions because they're natively baked into the browser (tab management, RAM management, and general organisation). It also assists greatly with its keyboard shortcuts, ad blocker, and distraction blocker. I recommend it.
