An element suggestion? Ok! 

My suggestion: Helium

Info: Helium with symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table. Its boiling and melting point are the lowest among all the elements. It is the second lightest and second most abundant element in the observable universe (hydrogen is the lightest and most abundant). You can make helium orange in color. Also, this is not a element suggestion, but I would like for you to add a setting called "liquid nitrogen can vaporise to nitrogen gas" and for the default, its off. It is friendly to vanilla saves and makes the game better.

strage matter:

glowing red and blue (randomly change to red and blue, and the hotter it is the faster in change color)

-Starting temp is 1200C

-Liquid

-Turn the element it touch to strange matter

-Will decay to quark slowly if not under pressure (pressure need to be above 150)

quark:

red, and glowing a bit

make white trail

-Starting temp is 500

-Move like PROT[proton]

-Decay to PROT[proton] and NEUT[neutron or dissapear]

-Can past trough other particle

-Create pressure

magnet:

grey

-Starting temp is 22C

-Solid

-Attract metalic element

-Become BMTL[breakable metal] when sparked (or when it melt become molten BMTL[breakable metal], melt at 2000C

RAYC: element that controlled by arrow keys and raycasts, if right or left arrow pressed it gonna change direction.

It displays 3d view in small window near elements panel. this window is dragable.

Element is grey.

FLCL: floats like gas and clones

LQCL: liquid that clones

PWCL: powder that clones

FILL: filling screen with ctype element

LATC: lke FILL but diagonal

PVPW: powered powder, acts like powder if powered

PVLQ: like PVPW but lquid

PVGS: like PVPW but gas

METR: like battery but output signal delay is cahnged by tmp

QTST: quantuum string, if touches element, makes it same setting velocity and eect the same as itself

TRIL: leaves trail behind

DC{LQ|PW|GS}: another versions of DCEL

AC{LQ|PW|GS}: another versions of ACEL

LQ = lquid

PW = powder

GS = gas

good or bad?

i have some more suggestions

Servos: This would improve building incredibily

Motors: Servos, but just a little different

Springs: self explanatory

Command blocks: This can do some cool things

add a object that expands and un expands and any thing it touches depending on the cornors of the object it would either pop the object or bounce off it, or make a "3d" object that interacts with 2d objects it would look cool even if it could lag the game

CPT

Custom Particle

A particle which you can change how it behaviour and etc via a little console, in how many directions it goes and such, the starting temperature.

If it goes through elements, like all or specific ones, or for it to have the same behaviour as PHOT for example.

--

If it "changes"(with the "s i mean that it won't fully change colours, just slightly get more blue, if it passes through a normal temperature FILT for example) colours like phot when it passes through GLAS/FILT.

Or, if it makes gravity like GRVT but isn't affected by it's own gravity.

And more as you may have some more even better ideas.

Or...

SBFK

Subframe Kit

A tool that allows you to make friendly to post(as in it doesn't use a element that is only on your Mod) and that would help a lot with the dark subframe electronic stuff that is quite hard to do, and certainly would bring more people into doing frame-fast subframe stuff.

It would have a interface for what you need to do, from the simple(supposedly) subframe SPRKs to serialization.

CAFE - Coffee. (Liquid) Made by mixing CFEP and SLTW/SALT + WATR.

CFEP - Coffee Powder. A substance that is used in making CAFE.

if you're Bri'ish just call it TEA and TEAP

my tpt magicaly disapeared 
i didnot found cracker 1000 mod it just disapeared completly
