Twitter Is Testing Two New Useful Features

If you’re an observing Twitter user, there’s a chance that you’ve already noticed two new buttons. One of the two buttons is titled “Shop,” and it’s intended for tweets containing links to product pages on a shop’s website. The other button is titled “Undo,” and it lets you undo a recently sent tweet.

Shop Button

The Shop button was spotted by Qatar-based social media consultant Matt Navarra, who first noticed it on his Android device. Tweets with the Shop button can be seen as alternatives to ads because they both serve the same purpose. The biggest difference between them is that ads are not organic, and many Twitter users don’t see them at all because they use various ad-blockers.

The color of the Shop button matches Twitter’s established color scheme, but it’s likely that it will eventually be customizable. If the button takes off, then we could see other similar e-commerce buttons launch in the future, such as a subscription button.

Twitter has also recently announced that it’s aiming to become a creator platform, so that’s yet another use case for this new tweet format, with exclusive subscriber-only content being just one click away.

Undo Button

While arguably less exciting, the Undo button is something all Twitter users can appreciate. It appears for five to six seconds when a user hits send on a tweet, giving the user a chance to change their mind and make the tweet disappear before the whole world sees it.

We expect the feature to result in fewer tweets with typos and embarrassing grammar errors, but we can also see it saving relationships and careers by making users rethink whether their tweet is really appropriate or not.

Unfortunately, there still hasn’t been any news about the prospect of an Edit button, which Twitter users have been requesting for years now. But because Twitter CEO Jack Dorsey previously said that Twitter would likely never implement it, it’s probably nowhere on the horizon.

AltoVolo has started taking pre-orders for its first electric vertical take-off and landing aircraft, the Sigma, moving the startup closer to commercial rollout. Customers can now secure a build slot with a £860 deposit and customize every detail online — from paintwork to seatbelt stitching. It’s the first configurator of its kind for a civilian eVTOL, mirroring how luxury car brands let clients tailor performance models before production.

The Sigma runs on a hybrid-electric tilting jet system built for long range and low noise. It can travel up to 500 miles at a 220-mph cruise, and is over 80% quieter than a helicopter. The three-seater weighs just 980kg and can maintain stable flight even if one jet fails. Safety systems include triple-redundant controls, thrust-vectoring stability and a ballistic parachute.

“We will be delivering an ultra-refined hybrid electric aircraft,” said founder and CEO Will Wood. “We believe there are thousands of customers for this type of cutting-edge technology”.

The first 100 units will come with exclusive materials and finishes. AltoVolo is also setting up a global service and maintenance network, with early planning for overhaul schedules already underway. The company’s focus on ownership experience echoes its ambition to anchor itself alongside established aviation brands rather than pure tech ventures.

To help new owners train, the company has built a full-scale simulator that replicates the Sigma cockpit in carbon fiber and leather. Pilots can log time toward a license using the system, aligned with the new US MOSAIC rules that ease certification for powered-lift aircraft. Certification work in Europe and the UK continues in parallel, signaling growing international alignment around light sport and eVTOL regulation.

Noise inside the cabin has become another design focus. Engineers are refining internal vibration levels and developing a responsive soundscape that shifts with each jet’s power load — part feedback, part theatre.

Urban air mobility projects across the Gulf and elsewhere are pushing regulators and manufacturers to meet in the middle. Dubai, Riyadh and Doha have each outlined plans for air taxi corridors this decade. AltoVolo’s hybrid Sigma, sitting between electric promise and aviation realism, looks built for that middle ground.
