Account names are added to the right of the app icon in the new revamped home screen.

Videos are not synced to your account. Videos are simply too big in size and will make the backend more costly. They are only added locally.

See if the problem is resolved in v5.0 (once released).

I absolutely love this idea! I will take a think of the whole architecture and add this into maybe v5.x or v6.0.

With the new systems in place for Instagram, Twitter and Messages DMs in v5.0, I can easily apply it to more like YouTube, Messenger etc!

These, however, will be in a later v5.x update.

This will not be happening. Otherwise, you would be having horrible adverts, annoying pop-up ads, watermarked images etc.

Only time you can get free in-app purchases is when using the beta or by winning a competition.

It should do already. If not, this will be fixed in next update.

Is this Twitter or Instagram?

Have you tried v5.0 beta? If not, please send me your email and I will add you in.
