When you create a group of shapes, you have often rotated a number of them into various non-standard positions. When you group them, the group as a whole is assigned a rotation value (I assume an average of all of them). It would be nice if a group could be set so it's rotation was at 0 degrees when created.
From a design perspective, this would make rotating groups easier. Especially with snapping on.

People can click the printing option and get it sent to their home like most apps

Currently, images are added to the art board, but I would love to be able to add them as shape objects.

Without this addition, it remains challenging to make interface mockups using Assembly (which is something I'd love to be able to do with it).

Not only mirror horizontally but also vertical

Input hex color value in the styles section.

books, microscope, atom, table, paper, pencil and so on

I just want to be able to download just the shape no other background.

when we group shapes it would be great to shadow and stroke as one, not every single shape in the group, at least let us decide it with a button

I think you should add diagrams of electronic components ( diagram of resistor, diagram of capacitor.......) so that it's possible to make circuit diagrams in the app.
Here's a link with the most common ones( http://www.zen22142.zen.co.uk/Prac/symbol.htm) if they would all be added then I'd definately use this app a lot more.
Oh and also there isn't a single app out there which allows making circuit diagrams easily so it would really be worth it I think.

Please, please: generate an office pack (paper, sheets, books, files, light, desktop, chair!
Would be so great!

I would like to download all bundles like other countries do because today I saw a food bundle when I was checking them. I would like to have them like other countries. Thank you.

The ability to select all shapes to group and move etc...

I think this Assembly application is much going better if Assembly Creator team Add a "SVG" Editable Vector on each shape.
Sometimes i want too trying to create some of my own shape to my Design but i can't, because shape is limited to edit.
Hopefully i can able to edit a shape somededay.

Please. Thanks.

It would be great to be able to do very basic keyframing, or being able to setup a series of "states" and export to gif.

Trash, a place where accidentally deleted designs are placed so that they can be restored again. Also a cloud backup support so that if a project disappears unexpectedly, we can restore it from cloud. Thanks.

I love this app and bought the total unlock but you know what would make all these shapes even more usable?.

A mirror two way, mirror four way type options.
That is just the start of the iceberg.

Kaleidoscope layout with a variable for 6, 8 etc and beyond would take one shape and make endless patterns.

Currently if I enlarge a pattern the pattern scales larger with the size of the shape...this is OK...

however it would be nice to enlarge a pattern shape and have the pattern remain small... in otherwords, not scale bigger as the shape is enlarged..

After working on a project with many many shapes, assembly became unresponsive and slow. Flattening shapes would be good to make larger projects.

Allow users to search for and add images from google, giphy, etc.
