Despite Mecabricks in most ways being more advanced than LDD the way to find bricks is slower. LDD has a part icon for each type, that could expand or contract. With Mecabricks it's more complicated, you have to click bricks and choose by text name not an icon, then scroll down if it's lower down, then when chosen the parts show but they don't all fit in so you have to click the arrow to show more. This is more steps and more convoluted than LDD, why?

Ideally, a customizable UI, with element icons expandable to show parts, with tear-off resizeable pallets/ windows & dual monitor support would be ideal, and make it the clear winner over Studio.
