Not so much a tip as a plea for a better way. I use swivels on my hooklengths but like to pre tie them and this is the only way I've found of storing them:

The swivel is tucked under the tab bottom left.
I have the same issue & have never really been happy with anything. I really don’t like the plastic sort or the rig boards as they are too big and fiddley. I'd be interested in peoples ideas too.
I used those plastic wallets you keep credit cards in for ages..as long as it’s a tight fit they keep the hooklinks separate and untangled and weigh nothing...

Just recently I started to use these and they are quite good. I use tiny map pins to hold the swivel and the hook (I don’t like pushing the hook into the foam)...
I struggled to find anything I was happy with for storing hook-lengths, then I found the MAP storage box, not cheap but very good:
Fast forward to just over a minute.
You can put your hook over a pin; even with hair, bait band, paste spring etc. etc.; and pull your loop, swivel etc. taught and push down into the foam and it will hold under slight tension (if you want it to).
If you do have something bulky for attaching to the main-line, then you'll need to make sure that the length allows this to fall between the foam slots.
You can continue to put one on top of the other and if the lengths are slightly out, the foam will still pinch it and keep it in place.
If, like me, you have banana fingers, then you can use something (gate latch needle?) once the hook is on a pin to pull on the loop, swivel etc. and push the line down into the foam with your finger tip starting at the hook end.
It may be a bit on the expensive side, but you can literally get hundreds of hooks tied and ready to go of all sizes and lengths*. Get one of those labellers, I think I spent longer writing out all the labels than tying hooks.
It's also got an adjustable measure thingy that you can use to lock and once mastered means than you can tie consistent lengths.
*My problem is that I can never decide what I want to use to load it and then I normally end up tying them on the bank anyway since I haven't got the right hook size, pattern, line length, strength, make, hair, band, scrunchy, alice band, spring, clip, stop
