UML 2.5 includes a new symbol for associations: the ownership dot (https://www.uml-diagrams.org/association.html).

It could be very interesting to include it in this wonderful tool.

The AppImage for StarUML currently crashes under Manjaro and Arch Linux due to including an old version of the harfbuzz library.

We can change the diagram background color, but not the editor's background color. So, it would be perfect to add this feature.

Please let us change diagram background color, which is now white. White is too aggressive for eyes in dark environment ... I would prefer to change to some greyish tone.

Bigger Canvas for ER-Model and other diagram. I cannot move to the edge of the digram unless I zoom out a lot, but the edge objects become inaccessible if I use normal size(e.g. 80%).

This has been requested many times. It was supposedly already fixed in version 3.0, according to this issue. But it is certainly not fixed in version 3.1.

For me it's an accessibility issue. Your otherwise excellent program is rendered (no pun intended) unusable, because 2/3 of the screen is a painfully glaring white.

StarUML does not allow an artifact instance to deploy to a node instance.

An error "Invalid connection (UMLDeployment)" is displayed.

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.

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.

I don't care if you only allow simple integers for sequence numbers, I just need to be able to reorder those numbers after I've inserted new messages or removed old ones.

This may be a feature already scheduled, but I can't think of another way to instantiate a template parameter in Star UML

I am trying to describe and capture timing information with UML. I have used the UML timing diagrams and timing constraints on sequence diagrams in the past.

Interaction Overview diagram is so much similar to the Activity diagram. It lets us to see the bigger picture of the project flow and shows how several interactions work together.

It uses different interaction diagrams(Sequence, Communication, Timing) and ties them together to make a single complete picture of the interactions.

If it would be added to StarUML then I can say that StarUML has all of the necessary tools to rock n roll!

Sometimes I need to add a logo to a diagram. Other times there is a project specific image that represents something well. I want to be able to add these images into the diagram or perhaps override the icon in a stereotype.

I think that an easy and useful new feature is include a Requirements Diagram. Currently it's not possible to document the system requirements using the StarUML software. I was using the Enterprise Architect and now I'm looking for other solutions. The possibility to link the user requirements and system requirements with the Use Case is interesting to help to control the whole process.

As a developer of a shared library with an API to document I want to be able to export the diagrams via command line arguments so that I can generate and deploy the documents as part of continues integration via Bamboo etc.
