Swapon -a not working

Hello again!
After awaking from sleep mode I saw that the system is too slow and also that too much of swap space is occupied. I decided to return swap contents to memory and ran swapoff -a. After that I tried to enable swap again by swapon -a, but it didn't work. When I read the manual it said that it enables swap found in fstab file. My fstab file contains only root and efi partitions and no swap.
So I have a question for the developers - why is swap file not listed in fstab whereas it must be?

Yes, swap should be listed in fstab by default. What way did you install Q4OS ? Please post steps for us to be able to reproduce the issue.

What way did you install Q4OS?

I installed it from a live DVD made from the ISO from your site (the one with KDE DE).

Please post steps for us to be able to reproduce the issue.

Are you serious? Really? Well, I can do that:
- open /etc folder in file manager
- open fstab file in text editor
- search for the record labeled "swap"
- find nothing
- feel embarrassed (optional)

Yes, this can be done. I actually got the ID from KDE partition manager. The question is why it's not initially there, which developers refused to answer. Did you also have swap missing from fstab from the beginning?

And what is this "sw" thing? It's not mentioned in the manual.
