I have tried to use it, but when selecting the enemy and then the animation, I can never see it like in the image.
That is because, probably, you are using the wrong text mask. If you use Bloodbane script (mine is based on his version), your value order is different from the default one in CMT, and this is why you don't see the image.
Let me show you how it works:
1- Go to Binding tab and paste this in "text mask"
Code:
@cmd position {frame} {x} {y} {z} {direction}
2 - Choose the entity you want to display, which animation from that entity you want to use and hit "show entity"
I've recorded a quick video showing how I do it (I am using
my custom method to make the grabbed animation, as it make the whole process way easier)
It's very easy to do

(I should make a full video tutorial someday)
PS: the tool isn't slow to display the target entity - its my external drive which is slow and that was the first time I've opened the tool today.
In the past I used OpenBor Editor 1.5.9, which has a friendlier interface for editing levels.
They are almost the same, and you have more useful options in CMT than you had in OpenBOR Editor (which I used too).
There are only few things you cannot do or you have to do on a different way:
1 - To drag an entity by it's shadow in OBE moves the entity up and down in Z axis, while to drag the character by it's body moves it up and down in Y axis. In CMT, if you drag the entity you will drag it up and down in Z axis, but you can change the Y in the right menu
2 - OBE had a mark which shows where the P1, P2, P3 and P4 will spawn on the stage, but CMT don't have it -
@Piccolo this could be an idea to add
3 - in OBE, you can add new entities right from the visual editor, while in CMT you don't (but you can copy and paste entities in visual editor). To be honest, doing this in OBE wasn't great because we need to take care about the WAIT/GROUP
Maybe you are missing some options from OBE, like stage declaration, properties:
and stage properties
But I am pretty sure if we guide Piccolo he could add it on CMT too
And compare how both tools display the same stage and how easier is to see stuff in CMT
OBE
CMT
in CMT, we can have the entities tinted by their group, we can see the minz and max z (the orange and purple lines), we can preview the HUD,
we can scroll the stages in the preview too:
In short - it's a more complete tool
