If you're not regularly using the Warpcast web client, why not?

Warpcast: desktop => app; mobile => app

Twitter: desktop => web; mobile => app

I’d do the same for Twitter if Twitter had desktop app.

What do you like about the desktop app?

What if I told you everything about the web app is faster / better / new features sooner / etc?

Personally, ⌘+tab/⌘+space to get to the app is more accessible for me than being one of the tabs on my browser.

I'd consider switching to the web app though if it's meaningfully better than the desktop app. I'll try the web app more and see if my habit changes.
