Please rework the tools palette. Some ideas:
1.
make it easy to use the full height of the monitor to show more tools
2.
make it possible to select / activate tools directly through the All Tools overview, even when they are already loaded in the tools palette. It's inconvenient and annoying to watch an icon blink and then have to go into that to select a hidden tool.
3.
make it possible to drag tools from All Tools that are already in the tools palette. Dragging should result in the desired tool on the desired spot, and remove it from the other position.
4.
add Search to All Tools
5.
add a favorites / recent used Tools section. Just like in the Swatches palette.
6.
make it easy to switch to the previous tool with a key (see how Cinema4d utilizes that technique)
