Given how often the items in the file and edit menu must be used, I find it silly there is no top button bar.
Why must we be forced to memorize keyboard shortcuts or do multiple clicks in order to do simple things like duplicate models or place surface on bed? These should absolutely be readily available buttons, not just menu items.
We should really be able to create our own top button bar with the functions we use regularly.
Additionally, the right hand button bar should be draggable, so we can move it to the top/bottom/left sides if we need, especially for those of us with 4:3 displays.
These super-basic software features which should be included in every software package, as there are literally hundreds of classes already available from the open source community which do this stuff.
