I am using Version 19.10 and I noticed 2 things.
When Copying Elements from a Flowchart to a Sequence, the Elements get ordered backwards. Probably the nodes in the xaml-file are in opposite Order. This can be quite a pain, when you decide to convert one of your xaml-Files from Flowchart to Sequence.
I used to create my xaml-Files with “TODO”, but noticed that even though I rename them after I completed them, the name is still in there. This is just a miscellaneous issue and Probably there is a reason for the first name to be kept. So a “TODO” tag would be a nice feature.
