Interface arrangement changes to save time

[maximka1812]

It can be nice to have miniatures panes on the left, as well as side tabs (with layers, filling and such) also towards the settings side, not opposite (as it is now, on the right).

Such way it is much simpler and faster to use mouse during mass editing.

Also, on pain panel during output you must be able to use CTRL or ALT + click to start drawing zone and it must switch for this page to Mixed mode - such way you save ton of time.

Also using space to see original page with original arrangement during page prototyping stage is very useful.
