General
The app's UI is good, but I think gradients should be removed as they're no longer trendy.
Separation from Corel - it would be better to treat Corel Vector as a separate, more modern and web-based product for a different user group.
Separate website? As a fan, I would like to follow Corel Vector's development and have a blog.
More flexible payment options. Upon entering the app, trial version and upgrade information is shown everywhere. Tools like Figma or Canva only show such things after trying to use a premium feature.
AI functions?
Tools
Layout design functions. I think adding an autolayout tool like in Figma would be good
Ability to change panel locations e.g., layers on the right, inspector on the left
Option to move the toolbar with rectangle, knife, text, curve tools to the left side, to make the GUI similar to Adobe Illustrator / CorelDRAW
