(If a part of the post doesn't make sense, just keep reading, it should be explained later)

TPT should have this toggleable feature where all powders/liquids have the same density. 

The density could be changed with the console or the PROP tool, just like tmp, tmp2, life, etc.

If a player has the Equivalent Density settings on (just like Water Eqv), all powders/liquids have the same density property.

However, if the setting is off, the powders/liquids start acting as usual (diff. density), but the density property will still save in the particle.

Two variables can be used, one for the actual density (if eq den if off this resets to the usual powder/liquid density, if den on changes to set density (continue reading)) and set density (changed via console/PROP, stored until eq den is on).

This came to my mind since I hate it when some powders and liquids have different density, meaning that you can't mix FSEP, THRM, and FIRW together to make an explosive, for example.

I know that some of you are reading this right now and thinking, "Just make a Lua script or something." First of all, some players do not have the ability to make/run script because not everyone is on PC. Second, Water Equilization was still added, meaning the developers didn't just go "meh, they'll make some lua script if they absolutely need it"
