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.

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%).

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.

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.

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!

It would be nice if StarUML could support modelling of Requirements and Test. I like the approach taken by Visual Paradigmen 11.2(http://www.visual-paradigm.com/features/uml-and-sysml-modeling/) by supporting "SysML requirement diagram". I tried to emulate it in StarUML 1 with an own model but it isn't quite practicable. If this feature would be voted, please take attention of text-wrapping for the elements and give a possibility to define own values (e.g. for risk). If it's not to much, the fields of the requirement-template should be definable by the user.

add sysml support to fully features for SA

Allow to decide the sort order of the elements inside of the explorer.
It would be highly convenient to have items ordered by default by name.

macOS started to complain that application needs to be updated for 64-bit.
Time to update!

snap packages have better compatibility for Linux distros with support for it because all dependencies come inside the packages. Tried to install staruml on Ubuntu 17.10 and 18.04 beta and failed because of dependecies

Please official support for 16.04 Ubuntu by using libgcrypt20 instead of 11
