Hi there
I was just wondering what tools / software you are using to create your responsive banners for mobile and also for landers?
I use Photoshop and Notepad++ only and check my landers on my mobile (I have some devices on android, iPhone and old Nokia).
I think photoshop is what most people are using to make banners.
As for responsive mobile landers - you can "borrow" landers you see in spy tools or through manual spying, and modify them. Alternatively you can build them from scratch. Caurmen's post here will help you get started:

Alternatively you can use banners/landers creation services such as bannerslanders.com.
As for text editors for editing lander code - Notepad++ as Mia recommended is great. I'd also suggest checking out Sublime Text.
Hope that helps!
Amy
Sublime Text and Notepad++ are both great.
I do have a new recommendation for text editor for editing landing pages: Microsoft's Visual Studio Code.
I know, Microsoft. But seriously, this thing's amazing. I've seen Linux users posting things like - and this is almost a verbatim quote - "Thank you Microsoft! You've revolutionised my coding experience."
Why? Well, it has a lot of very cool features, it's fast, it's lightweight, and the UI's really good. It's also a full-fledged IDE, so if you need to go from writing HTML to debugging Javascript, it can do that too.
I'm really enjoying using it.
Thanks for the help Amy & Caurmen 
Photoshop for banners, as you can animate them right in photoshop.
And for landing pages, my coders do it by hand in notepad++ pretty much. But I heard good things about adobe's creative HTML editor
Thanks iAmAttila!
