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

It' better to add more icons like a weak entity, weak relationship to represent the relationship among entities. For now, I cannot even draw a diamond to show relationship.

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.

The wordWrap property does not take effect.

New notes in 3.1.0 can't wordWrap set to true can resize width less than the line length. And the text can only show in a single line.

Interfaces are awkward to place in a model.
You have to place the round-end first and then haphazardly try to connect to it with an association.

It would be far better to simply plus the whole lollypop in one go.

EERD are ERD with a couple of extensions.

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 can change the theme to light or dark, but in both themes the text remains some form of gray that's not as easy to seperate from the background as it could be. If I switch to the light theme the shadow effect even makes the text look slightly strange.

Any way to change the text color so the text will stand out more will be highly appreciated.

Current namespaces is in the following format:
"from package"

Instead have namespaces displayed in the following format:
"package::subpackage::name"

The scrollbars are currently very hard to grab. For users who use the scrollbar ( I personally use it for horizontal scrolling ), this is actually pretty annoying.

StarUML treats Pen as a mouse.
So I can't draw any associations between classes because it acts as a scrolling.

Create the ability to align text in relation to the element to which it belongs. For example: Top Left, Bottom Right, Middle Center.

Vertical Alignment should offer: Top, Middle, Bottom
Horizontal Alignment should offer: Left, Center, Right, Justified

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

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.

i hope have a extension to generate golang code

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?
