To speed up work you could press for example "C" key and you have acces to context menu under your cursor. It could show different options for different types of objects.
For example:
1) Shape / shapes - menu contains last used colors (alt clicking on color applies it to border), align, and other tools. (example image attached)
2) Text - menu contains styles, fill with lorem ipsum, text alignment etc
3) ...
It would be super awesome if you could customize that menus.
Another idea is to maybe rebuild/add to right click menu to be more context aware and more visual (more icons grouped into sections and less text).
