Hi there 
Ashley and the Construct 3 Team,
I am a Standard Early-Adopter of Construct 2 and loved some of the features there. I got to use the application on and off over the years but never really dived into it full time until I started playing around with Construct 3.
For someone with very limited knowledge on how to program, I'm loving every bit of what Construct 3 has to offer to an artist.
As I am getting used to Construct 3's interface, I have a small UX wish-list for some of the features that I use very often. Some of these suggestions already exited in C2. This wish-list is only suggestions to help improve C3's experience slightly and make it 'feel' similar to most art-friendly interfaces (like Photoshop, Animate, etc).
Layers
Layer - Left Align Content
Left Align the content in each layer. The content now is fitted a bit more tighter to the gray frame of the 'Layers' panel, and it gives users a sense of precision when hitting the Preview Toggle button.
I love the way C2 had this left aligned, but the icon alignment corresponding to the layer icon was misaligned. Hoping C3 tackles this well
Feature: Toggle Preview and Lock All Layers
Use Case : When working on projects with multiple layers, toggling all layers becomes a bit cumbersome. User has to click on each individual layers preview / lock to perform the desired action.
Solution Add a shortcut feature icon to 'Toggle All' for Preview and Lock.
To make this feature more intuitive - Holding Ctrl on any layers 'lock' will toggle that specific layer to it's opposite state and all layers will get toggled to that selected layers final state
Holding 'Alt' on a specific layer will not affect the selected layer, but toggle all other layers to the opposite state of the selected layer
Ability to Rename 'Layout'
Use Case : User has to go to Project / Layouts to rename the selected Game Layout.
Solution Adding the rename icon next to the layer header gives users the option to quickly rename a Layout.
I'm just one of the many use cases C3 is being designed for and I was hoping the team would find this info useful and hopefully tackle these minor inconveniences.
Cheers to the team for all the rock solid work and update!
