In terms of responding to external conditions, it would be more appropriate (than manually switching each application) to respond to system settings and its automatic / manual day / night mode switching. Then the settings in Preferences would become added - Day / Night / Automatic mode.

Yes, It is.

It would be interesting if we have a button on main interface for aff pub, aff des, affinity photo as sun/moon/both appearing for turn on/off themes.
Suggestion attached.

Preflight user comments
Preflight user comments can be added to objects in your publication, creating a custom check to be made prior to print or export. This has many uses, including the ability to:
Check specific layers are hidden or visible at export. Check text and picture frames are populated. Check text frames with placeholder text that may need replacing. Check images that need copyright checking or creative approval. Check images using temporary colours. Check copy. Ensure copy is approved. When a user comment is added, it will be listed in the Preflight panel to be checked later.

Hi folks,
I suggest implementation with variable data from an excel or any office datasheet. I usually do event folders that need scheduling with constant editions in cases of changing time, day, speaker, title or photos. It´s extremely necessary that changing my datasheet automatically adjust my layout using variables by tag or other similar way. It´s relevant that interface doesn´t ask for manual insertion fields and the dialog box offer tags to drag and drop like into document, permitting applying styles into them with personalized adjusts. It´s just a suggestion that I´d love if happen!
