I've been using the mapping tool you've got. I've tried a few web-based mind mapping tools but I like yours the best so far. One of the key features I'm using is attaching images. I use a lot of images (graphs, charts, etc) because I'd like to use this as sort of a presentation tool. Most of the other apps don't offer much flexibility in terms of attaching images.
I think I've figured out most of the features of your's but I still have a few questions for things I can't figure out so I was hoping you could help.
1) How to control the order of the layering of images. For example, I have several nodes at the same level and each has a child node with an image. I want the second one I open to appear on top of the first one. Is there any way to control this?
2) Focus control. I was wondering if there is a way to automatically bring an image or a node into the middle of the screen when it's selected. Some others (like MindVectorweb.com) employ this feature and I find it really helpful. It prevents me from having to keep moving the nodes and images so they can be easily viewed.
3) See below. When I have my Chrome zoom set to 90% or 100%, part of the border color pop-up in the Inspector window is blocked by the top of the window area and is not accessible. And, I can't move the Inspector window past the bottom of the page. Hopefully, you see what I mean.
Thanks a lot and keep up the good work!
