Steemit resources. What's out there?

I'm using this platform (Steemit) in a more intensive way and I'm finding that people is creating a lot or resources to add to this platform and use it in a more professional way. By now, I've find (and used) the possibility to attach images to the posts, just dragging the images, but looking at others I'm finding more resources like:

APP
At Android or iOS, you can have a great app like eSteem, with a great post from Hive account@kyusho about this app, here. It's made by the user Hive account@good-karma and I find it very useful!

MAP
There is a great resource to locate the posts in a map, if the owner acceded, is Steemit World Map. This will help to locate people with their located posts and, maybe, organize future trips.

VIDEO
Tired of Youtube politics? Try Dtube!! It will help this decentralized platform.

With all this resources you can keep your profile updated and your entrances will make a difference.

Do you know other resources? I ask as I'm newbie and still learning.

Thank you!
