This doesn't really sound like a "move it" feature to me. Maybe post about it in Find It instead? Clicking on something to find it in the Find It menus sounds very reasonable.

(I know there's a mod for this for Roads, but I'm not aware of one for other things.)

I mean Props, Trees and other things already in terrain. And when you select them with Move It, you can see a tip window when mouseover or stop on them, and know what is this.

Also can Move It add "Copy" module like 'Prop Line Tool' Mod for other construction like this asset.

Can you elaborate on how the new Copy would be different from the copy button that Move It already has?

It's like 'Prop Line Tool' mod did, but for other construction.

For "Hexa Structure" asset, it's a electric construction not a prop. Now I want to copy "Hexa Structure" to cover the whole road and If road build on terrain which is uneven, and I need to copy one by one and align them, and some road location can't let it to good align with now copy button.

So, add the new 'Copy(name like Array Copy)' module like 'Prop Line Tool' mod did for props, you can select a construction and you can copy and auto align to create a line, curve etc..

(Sure, someone will use it to do crazy things, like "A Line Eiffel Tower", "A curve Nuclear Power Station" etc......)

For now, when you check someting, like a tree, and don't know what type is this.

So....the picker feature that's already in Move It...

What would be really useful (and similar to the OP's idea), is enabling/disabling picker features by pointing at an object and pressing a key. That way you wouldn't have to think of what type the item is, then go in the list to disable it (and do repeated selections, before you find the correct combination of item types).

E.g.:
1) use marquee tool, but end up with too many items of wrong types
2) point at an unwanted item in the area and press some key combination to remove that type from the picker prefences AND THE CURRENT SELECTION
3) repeat 2 as long as there are unwanted item types in the selection
4) continue with the items you want that are left in the selection.

Turn on the Debug Panel in options, this gives information on the currently hovered item, the selected objects and some more technical info.

There is a mod that lets your remove cims, I think it's TMPE.

This does EXACTLY what you suggest.

Not only does it tell you what the object is, but it also goes and gets it for you!
