I have no knowledge of which of these are "the good stuff" but this will give you an idea of what i mean.

Maybe these would be better for you then putting holes in the wall?

(There are lots of other variations on this theme.)

I've noticed Costco also has these, if you have a membership you should check there.

I can totally relate to the reluctance to put holes in your wall. (Maybe that's not the issue, but if it is...)

I don't know if there's a one-step answer, but I have a three-step one.

Here's the magnetic sheets I was talking about:

magnetic sheets

I bought some plain black magnet sheets and just cut some shapes out. The smile was three sheets wide.

I didn't bother taping them together, just stuck em the car.

Magnet sheets

A magnetic dry erase board and magnetic tape for tracking initiative. We cut strips of the tape for each character and sharpie the character name on it, then I drew little skulls on the side of six more. Then when initiative is rolled we just write the number in dry erase and move them accordingly. The included magnetic eraser can indicate the current turn, or another piece of tape can be decorated! We also ended up making custom status markers for spell effects and the like.

Board & Tape

We also use page tabs stuck to their bases to label the enemy minis to make tracking of individuals or groups easier.

Page tabs

This is a bit lengthy, but I will try to get across all the different combat tools and ideas that I have ended up using to help me stay organized and efficient in combat.

To start, I use a homemade magnetic initiative tracker. Only costs about $5 to make. I got an 8x12 galvanized steel shingle from Home Depot for a dollar, and some magnetic tape that I wrote the Character names on. Then made some spare blank magnetic name tags that I put tape on for dry erase markers to write enemies on. I just slid this into a paper slot of my DM screen. It could also simply be held on via strong magnet on the other side of the screen.

Then I just use sticky notes to track different damage on the NPC's. If they are weak I will have 2-3 on one sticky note or use just one if it's something big. Side note I add up to their health in a fight as I can do addition faster then subtraction in my head.

The sticky notes are also nice for writing down the names of spontaneously created NPC's, places, etc.

Another thing is that I got a cheap Chess set and used the pieces for the enemy NPCs. Though they could be used for both if you want. Then I just wrote numbers on the pieces to make keeping track of them easier. Here is an example of the chess pieces I use at the end of one of my sessions. As you can see I have also adopted the lego character figurine idea.

If possible I try to print the enemy Stats before hand, and if not I have 3 bookmarks in my monster manual for keeping multiple types of enemy stats readily available. I made this to make keeping track of generic enemy humanoids simpler. I used this to help with the encounter pictured earlier. I used the different types of pieces to signify the different stat blocks, and black and white to signify good and bad guys.
