Currently there is no way to get back the associations which have been removed from the diagram, but not from the model

Currently attempt to open another model fails almost every time in error (OSX). Only indication of that is a quick error message which is shown just briefly and easy to miss. After failure StartUML opens previous model which could lead to loss of data if user doesn't notice it. Second attempt to open the model works always.

Please fix

I am using StarUML as an agile means to communicate initial sketches of system design prior to any code being written.

As such these designs typically explore hypothesis about the system design. It would be great if the diagrams could reflect this by looking more informal and hand drawn.

I think the current rendering of the diagrams looks great as formal designs.

For Agile development, it would be great to be less formal and convey to the team they have wiggle room to make adjustments on the design.

EERD are ERD with a couple of extensions.
See https://www.lucidchart.com/pages/enhanced-entity-relationship-diagram
I'm currently needing those to fulfill a work requirement.

Most apps on the Mac use double click above the toolbar (the bar containing the Close, Minimize and Maximize icons on the left) to resize the app to fit the screen. This would be very useful since the app always starts as a partial screen. Automatically fit the app to the fit the screen at startup also would be an alternative solution.

i hope have a extension to generate golang code

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.
