Add ability for concurrent requests

[sunny-b]

First off, congrats on building this tool. This is the type of tool I've been wanting to build for a long time but never got around to it. I'm a bit jealous you beat me to the punch but am just excited that something like this exists.

I'm currently using this tool to make some diagrams for a blog post I'm writing. However, the blog post deals with concurrency/parallelism and that's something I wish you could visualize with this. I can kind of get around it by creating multiple of the same components and overlapping them, but still not quite the same.

I hope to contribute to this project in the future as it's definitely an area I'm interested. Possibly this feature is something I could work on myself.

In any case, thanks again for building this tool.

Thanks for suggestion. I'm currently working on a lot of things so I don't know when will I get to this, but it's a good idea.
