Please add support for C code!!

Input math expression as string on diagrams and then show it as math formula.

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.

Make it possible to embed StarUML into custom web applications. Offer application license. Ability to conveniently collect data for purpose of storing into database and populate model diagram from data pulled from database.

I'm using Qt framework for GUI layer with some pure C++ projects.
StarUML is really nice tools for investigate the software design however current version of this is not support Q_OBJECT in Qt based header file.
The result for Qt based header files, there is no class name in the class 'box' on StarUML.

There is yet another way to model the software architecture with C4 models where C1 is a helicopter view and C4 is a class diagram zoom level (see more https://c4model.com/). Components used for C4 modelling are simple but have some notation rules.

State diagram transitions, as you well know, are in the format:

Event [predicate] / actionlist

However, the edition dialog does not appear to make evident that simplicity, but offers, among others, the following entries:

• name


• guard

This is not identical to EVENT [pred] / ACTION LIST that I would expect to see.

Perhaps I misunderstood how starUML creates UML2 compliant transitions?

bug：windows下没法同时开启多个项目。

比如已经开启了A.mdj文件。然后开启B.mdj文件。虽然开启了两个窗口，但是显示不正确，会变成开启了两个A.mdj工程。

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

Hold the right button to drag the view, like CAD and Photoshop, which is the most convenient.

I know the main concept of this great tool is support UML for engineer work (mostly in the backend). But, have you ever think in give also a little bit of support for UI/UX prototyping? It don't need to have a complete palete of component, but just the basics. Freelance coder sometimes have to model this for their clients, and having the chance for doing this from the same tool they use for another models, would be great.

can change the system language and font

When we are designing a system, is common we change our mind about use an interface or class. Models is just a draft until they generate code.

Would be nice be able to change an element originally create as interface to class and vice-versa.

User would like to have the ability to add a generic type (example: LinkedList<String>) as return values from methods in classes in Class Diagrams. Currently, only primitive and class types are allowed.

I use colors to enhance diagrams following Peter Coad's ideas with an extension by Carlo Pescio for design. I'd like to have a set of predefined styles I could easily apply when I create a new element

I'd like to create simple markdown documents in the project in order to describe how the application works or how consistance issues are solved.

Documents should be exported as pages in html docs.

Allow the representation of generalization/specialization relationships in ERD diagrams

I need this feature

On activity diagrams, object flow and control flow are indistinguishable. And I sometimes use line style as another kind of visible "stereotype".

Why not allow to set line style for all types of connections?

Currently I can place a dot or colon or other non alphanumeric character in the name of the element only if I edit the name in the properties window but not in the editor interface. I would like to enter these in the editor.
