The sub-processes child to parent link does not work if you use "<" or ">" sign in the name.

I think this has to do with the XML backend, I have shared the XML of a mocked-up process.
In the below image the parent subprocess link does not work. For sake of clarity the actual name of the subprocess was "Play <= Yes"

However, if I remove the "<" sign it works as shown in the below image.

Also, in terms of functionality it would be great if Rapidminer Studio supports subprocess child to parent navigation via mouse forward-back buttons.

While it shows up as "<" when you are looking at that subprocess, that HTML tag changes to the "<" once inside that subprocess.
And, once inside the child subprocess, the parent subprocess link works, again with the "<" showing up in the name.

Thanks for a quick workaround, this helps for sure. In my actual deployment, I replaced it with less than as the words.
I thought that I should bring it up to RM Dev team.

the buttons to navigate are indeed very simple HTML <a> tags. By using <> you're creating an invalid syntax and thus breaking them. We can escape the name in the future, then the problem should go away. Scott, can you create a bug ticket for this, please?

Is there a way to extend similar functionality to the Execute Process within a Process?
For example: In the process below, if I double click on 'Execute 01 Text pre-processing' it opens up that process, but there's no way to navigate back to the parent process in the UI.
Its a much easier way to navigate to the parent process when we have tons of Executeprocess operators in one process. I have been asked by many users asking for this.
