Please add support for C code!!

One of the cardinal rules of documentation is always have a legend. See e.g. Documenting Software Architectures. It would be nice to have the option to create a legend. Bonus points if StarUML can automatically generate the legend based on UML elements in the diagram.

We can change the diagram background color, but not the editor background color. This is by far my biggest complaint with the tool and the one thing holding my team back from adopting it.

To be clear, I'm referring to the area of the tool with the grid background. The one that displays all of your diagrams.

I'd really like to see an option to lock a specific UML element to the workspace, so that if someone is making a namespace and has a lot of sub name spaces to move around they can avoid clicking on the containing one. I'm not sure how often people run into this when working with it, but I've found it somewhat vexing.

We should be able to, for example, double-click on "Attribute1" to select it, then right-click to paste from keyboard. It is possible to paste using Ctrl-V, but doing that many times gets annoying.

Add F2 for 'in-place' rename at least in Model Explorer.

Use case:
- Bob wants to rename element MyFirstClass in the model explorer
- Bob browse for MyFirstClass element in the Model Explorer
- Bob press F2 when on the MyFirstClass and in-place renames that element to MySecondClass

Is there a downloadable user's manual for StarUML?

how to convert a sequence diagram into a communication diagram (collaboration diagram)?

como pasar a español?

It would be nice if a usecase descriptions can split in multiple requirement-items. Each items needs a short text field.

Update extension GraphQL for StarUML 3.0

several bugs appear on new update

Open a diagram in other window but not at the same viewer.
example: an UseCaseDiagram on the primary display and an ActivityDiagram on the secondary display, both on the same project.

Thank you very much for adding in V3 the capability to copy diagram as an image to the clipboard!

Would it be possible to set transparent background on the copied image (or not, selected eventually in the user preferences)?

Thanks!

It would be great if you could add Parameter to Activities (Activity Parameter for Input and Output of Values).

Would be great if there was an extension for visual studio
