Many packages allow panning with the wheel of the mouse held in. This allows very fast panning which is very useful for large diagrams.

I need to export, import 'PlantUML'...

The Linux version of StarUML is currently only a .deb package. You should build it as .rpm as well, to support distributions other than Debian/Ubuntu.

Support multiselection in Explorer

Full screen mode for the workspace and separately for the workspace with instrument panels.

Currently the decision tool/shape in activity diagrams has no label to type in to it. It’s essential it has one. Also, it would be great if this text wrapped nicely to the diamond shape that encloses it.

If you're behind a proxy server it is not possible to load Extensions.
Other solution: Manually installable packages.

Just like in programs like Photoshop or Sketch - pressing and holding spacebar puts the program to "dragging" mode where you only can drag the canvas around instead of its elements.

As in many other design software, you can also use the space bar. Please be extremely useful, it is an excellent user interface pattern.

It would be nice to have a "snap to grid" option so it becomes easier to position elements next to each other.

The original's ability to export into a Word Template was brilliant and i truly miss it. For those that don't know - the original StarUML would export all of the diagrams, and notes/descriptions into a Word document. You would tell it where to put the diagrams etc. via key words in the Word Document template. it was an awesome way to maintain documentation, i could use our regular company documentation templates, add the keywords into the document template and bang.. always up to date, looks fantastic.

As an enterprise architect, I use ArchiMate for high level modelling and UML for more detailed modelling. It would be great if StarUML could add ArchiMate support!

In "Explorer" moving things to be sub items of diagrams seems to be a single item at a time experience (unless i missed anything.) Would save time to be able to control-click or shift-click to select multiple items in explorer to move.

In large seqence diagrams, we should be able to scroll down to the lower portion of the diagram. As of now in v2.8.0, we are unable to scroll down to the lower portion of the diagram, under zoomed in condition; and when we are zooming out just enough to see the lower portion, we are unable to view what we are working on, unless we use a microscope.

Generate class diagram and Dependency diagram from existing project.

we see lot of javascript code on web and it is very difficult to understand it but it is easy to understand and visualize the code via uml diagrams.
This way we can save lot of amount of time.
Perticularly useful who came from C/C++ background to understand the javascript code in fast.
I would like to know why nobody thinks in this way?
Please do update me if any such tool or procedure already exists?
Even I am happy to contribute for the same, if required.

Thanks,
