Can we change the look and feel of the application including colors, fonts, branding, e.g. through CSS?

Yes, you can change the look and feel of the platform with customizable branding settings for the logo, colors, fonts and other design element options like outline and corner rounding. All Google Fonts are available for free as part of the platform. You can choose to customize the subdomain by adding a custom domain like ideas.mydomain.com. It is also possible to remove Ideanote logo and branding from the platform and emails. You can also add custom JS and CSS code on top of these inbuilt appearance options to change the look and feel even more.
