I remember reporting about cursor movement being a bit unpredictable - you told me it is graphic in its nature. I can buy that, even if I almost do not use it anymore because it almost never does what I think.
However, the selecting mechanism in Dorico is also unpredictable IMO to say the least. One example: Right now I wanted to select some chord symbols and found that a “normal” selection of the bars involved does not include the symbols. I lassoed the first symbols and did a shift click on the last ones in the row. Nothing. To select all the symbols I had to ctrl-lasso bit by bit until done.
Yes, I read about selecting things with the keyboard etc. is in the pipeline, and I guess that there are reasons to why the chord symbols are not included in the selection. But I do think that Dorico would benefit from being completely consistent and predictable in how things are selected and in how things are copied. And please, consider including articulations in the filter.
