Do you mean the whole Studio ?  Shift Ctrl H
 
If you want individual panels, you will have to set a shortcut for them in preferences.
 

 
One thing you could do is contract a set of panels by double clicking on a panel name, like "Layers". That will contract that group. Click once on a panel name in the group and it will expand, ready for use.. Just place your favourite panels in the group that you leave open and put the others in the groups you contract until you need them. You can drag panels between panel groups to arrange them as you like.
 
In the images below I have contracted two of the panel groups. If I wanted Layers or Swatches, I just need to click on the panel name and it expands, ready for use.
 
You can add new groups to make four or more panel groups. In the third image I have four groups. In theory you could have every panel in contracted groups, ready to use when you want them.

Hello,
 
I'm just starting out with Affinity (AI user), and i found some User Interface incosinstencies. One of them is checkbox and radio button behaviour:
 
Case Example - Pen tool
Some button groups Mode, behave like radio buttons - you can select only one of many, and one of them always has to be selected.
Other button groups, like Snap, behave more like checkboxes, you can select many, you can select none.
 
It would be great, if user interface would distinguish it. There are obviously no standard "web" form elements in main UI, but there are some ways to distinguish it - for example rounding corners of multiselect that is just "select one only" type.

Unfortunately, this goes even further. For instance:
There is no visual distinction between trigger buttons that invoke an immediate action, such as Reset Selection Box (Move Tool), and the “radio buttons” and “checkboxes” you mentioned. There are standard check boxes, such as Lock Children (Move Tool), that perform the same type of function as your “checkboxes,” for instance Show Rotation Centre (Move Tool). There are detached “checkboxes” that systematically belong to the same group, most notably Snap Off-Curve Handles (Pen Tool). There are numeric input boxes with a flyout menu and a see-saw button, for instance Kerning (Character Panel), and on the other hand, there are numeric input boxes, for instance Paragraph Leading (Paragraph Panel), that perform the same type of function but lack the see-saw button. Though it is clear that visually distinguishing all these cases would create a mess on screen, maybe it would make sense to have button combos for the “radio” type buttons and detached buttons for the “checkbox” type buttons and the “trigger” type buttons. Hmm …

Hello,
 
When I'm in the move tool, when switching to hand tool (which i do often), pressing H again will get back to the last used option. For me it's very unintuitive, becase as power shortcut user i use them a lot switch between many options as well, I don't want to remember what option i just picked half second ago. Especially that i tend to double tap something on the keyboard which is maybe a bad habbit, but it causes me some frustrations ( again Hand tool example - and yeah i use holding spacebar as well in my workflow in case you wonder:P ).
 
If there are good reasons to have this feature then it's fine for me, but ability to disable it in preferences would be great.
