Did you really rebuild Thunkable X from scratch and not include a possibility to copy items or a full screen? 
I cannot find anything like that in the docs or the platform -.- Even Makeroid (now Kodular) managed to add this ON TOP of the existing app inventor platform 
also do you have a date when finally the icons for tab navigator will be available?
)Itâs very hard to make anything besides Hello world (or really simple app) with Thunkable X, and I really want to give it a chance.
Yeah unfortunately X is really poor (at this stage) and to me it seems ridiculous that they made this version a paid, finished product while every other company would not even call this a Beta but much more likely an âearly Alphaâ stage⊠too bad that Thunkable is heading such a bad direction right now - I was really a huge fan but for now it is unusable for me, because you cannot create even the simplest - meaningful - appâŠ
Nobody needs floods of stupid âHello worldâ or other useless test apps in the app stores - this is exactly what Apple is fighting by mostly forbidding/restricting Apps created with such creator platforms⊠Thunkable Classic was great since you could really create meaningful and beautiful apps but Thunkable X is unfortunately really bad for now. I think it will improve but I also think it was one of the worst decisions to end the beta stage in this early development stage and even charging for a âproâ version that is not at all âproâ right nowâŠ
I personally wonât pay a cent as long as this is still lacking so many essential features⊠They should have stayed with the Beta and create a powerful platform together with feedback from their great community and THEN launch a great product out of Beta and start charging for PRO (I have no problems with a PRO version at all if it is a finished, nice product)⊠Not launching a half-baked totally worthless version out of beta and trying to improve it whilst already charging money for itâŠ
cheers, Chris
Well, blocks at least can be copied with Ctrl-C, Ctrl-V ^^ (not mine, just read it here in the community)
I will buy if this feature available, thenâŠ
This feature is not available, but you can do it very easily 
When you start making your first screen (which weâll clone later),
do not add components in the screen;
take a 100% x 100% column, and add the items in it.
See this tutorial by me -

Thanks! 
Components can be copied
Put everything in one main column -> copy main column, done.
Just to expand on Maxâs suggestion @ariadriantoy0t, thereâs a full description of how to do this sort of thing here:
If there are multiple items within it it is likely to just crash the site and not work at all - at least that is my experience
Hi there,
What you have to do?
You canât duplicate the screen,but you can duplicate each columns.
Therefore,You have to set each screensâ content inside a column.Lastly,just duplicate that column will be done what you are looking for.
That is what I just wrote before: when having many objects in that column the site is likely going to freeze and not copy anything - that happened several times to me also it seems to become unstable and not sure that progress is being saved afterwardsâŠ
the tutorial link doesnât seem to be working for me @kartik14
Sorry,
I have updated it, now itâs changed to a representative video.
Thanks for reporting 
@Chris @Avram @ariadriantoy0t @maxb
Delighted to announce that this feature is now available in Thunkable!
Yes you actually can duplicate coponents in thunkable, there should be a two-page image on the right of your screen click and boom
easy way:::: Save a screen to my screens then click on add screen and select copy from my screens voila !!! the copied screen is available !! 
Is my Idea working?
