Here are some of the bad experiences I had after updating from v22 to v23.
On opening a group by double clicking on it in the drawing, the group does not open in outliner anymore.
Double clicking an entity in outliner in order to open it for editing does not work anymore.
Selecting a list of entities on the same level in outliner (click first one, shift-click last one) in order to rename them or make them a group etc. does not work anymore. You now have to cltr-click each entity separately.
Moving selected groups/entities from one group to another in outliner does not work any more (you now can only move one single group or entity at a time).
Right-clicking selected groups/entities in outliner in order to make them a group etc. does not work anymore (you now have to right-click one of the selected entities in the drawing to do this).
On exploding a group in outliner by right-click, the parent group closes instead of staying open. Furthermore, sometimes the names of the exploded child-groups/entities change to “group” (1x undo repairs this).
Typing ctrl-z repeatedly used to “undo” as many steps. This does not work anymore: only one undo is possible (now one has to revert to button-bar).
Something is wrong in indicating the material assigned to an entity. After changing the material of a nested enti-ty, the parent entity shows the same change of material for considerable time until it corrects itself.
Don’t know if some of those changes were made deliberately (like maybe the first one mentioned) or are bugs, they annoy me to the max. I am using SU since 2007, always with great pleasure and satisfaction, but this enthu-siasm lately waned considerably because of the little progress made in developing (not listening to the many suggestions/complaints made by users) and specially now the things I mentioned above are seriously hampering my workflow.
I speedily returned to v22, hoping things will be better in the next bug-release.
p.s. Also very annoying for years: After entering an entity-name in the entity tray, giving “Enter” does not close the name-field.
