I wrote my bachelor thesis about Robot Framework. The biggest issue i had with Robot Framework was the lack of support in IDEs. Initially you were suppose to work on Robot Framework in RIDE (dedicated IDE build on top of Eclipse) or use a Eclipse extension. I believe both of these are not supported anymore. I like Vim, so i wrote a package, which helps users when developing with Robot Framework. I also created some pull requests for Vim ALE to also support rflint.

We also used Robot Framework at work for automated testing, worked like charm.
