Dear sir

I noticed some issues with flow maps:

1. Selecting "Dashed stroke" seems to have no effect. The rendering of the flow-map does not change.
2. Changing the opacity does only effect the lines, but not the arrow-heads of the lines
3. Some texts of the English window "layer settings" are in French (for filtering by distance and/or intensity)
4. The link type (exchange and bilateral volume) and the link size type (proportional and graduated link size) can not be change anymore after "creation". I tried to change these options afterwards in the "layer settings"-windows, but this is not possible. I guess this is "by design" because of technical reasons?
5. In the "Legend setting" window of a Intensity flow map the Legend layout "Stacked" did not work for me. Stacked appears the same as vertical.
6. In the "Layer settings" window changing the "maximal size"of the line did not work for me, when at the same time the "on value" was set on the maximum. Setting the "on value" on a smaller value than the maximum value allowed me to change the "maximal size" of the line to another pixel-value.

Kind regards

Kurt Trinko

ps: I enclose a simple test-project
