When adding events and guards to statecharts using the inline textbox, the event component does not seem to appear in the edit section for the transitions. Also editting in the inline textbox for transitions usually fails ( eg guard not removed). The event-guard-effect interface needs to be simplified and less buggy.

any chance to have starUML on iPad?

Currently it is not possible to successfully select a template parameter as the 'actual' of a template parameter substitution from the 'Select type' list, as doing so results in the error

Selected element (?) is not an instance of a UMLClassifier.

However it is possible to create a reference to a template parameter by entering the parameter name in the actual's input field and selecting the desired parameter from the suggestion list. However this become very cumbersome.

A reference is important because it allows changes to the actual's reference to propagate automatically e.g. renaming the source template parameter.

The activity diagrams become exceptionally large when we are unable to have line wrapping (or multi-line support) in the names of the bubbles. As a result, the bubbles can become greatly broad and squat, hindering readability. See the following link for an example:

no icon for windows in ubuntu 18, you can try to install staruml on ubuntu 18, open a window ,you can see it

Please add connector symbol to represent that the diagram should be connected with other (part of) diagram.

If it is possible, I want to work with tiled multiple diagram at the same time and in the same window.

example : Something like diagram thumbnails but I'd like to interract with their inner elements directly.

Advantage :

- Working with multiple diagram and updating the model of the project instantly.

- Having a global vision of my project without switching from a diagram to another.

In the dark theme the user interface font is small and very difficult to read on my Ubuntu 19.04 system in version 3.1.0. It's like 9-point light grey on dark grey. Can you provide an option to increase it? Or allow users to provide their own themes?

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.

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 have 4K monitor and the GUI text is too small I would like to increase it.

Save last main windows size and restore it when program is opened. Windows 10.

i used bitbucket a lot, I'd love to be able to install extensions from there

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%).

I use many Diagramms and arrange them on the left handside "Working Diagrams". After closing and re-opening the file, the order of the "Working Diagrams" is set to the order you opened the diagrams, and not the one you had on arranging them manually. I would like to have the order of them persisted (should not be a big deal, shouldn't it?).

This has been requested many times. It was supposedly already fixed in version 3.0, according to [this issue](https://staruml.uservoice.com/forums/245359-feature-request/suggestions/14948286-diagram-background-color). 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.

I literally select ever class and interface and enable this option. Would love if I could configure this to just be on by default when I create new class or interface elements.
