Improving the sizes of headers and overall spacing, standardizing CTAs, separating navigation from content, and creating visualizations that drive users' attention.

Increasing the header size, reducing the size of secondary text, making buttons look like buttons, providing a better content structure in the sidebar, and visually cleaning the main content area.

Keeping context when opening information from the calendar, significantly reducing the screen's real state to display extended information and navigate through it, and improving the visual appeal.

Increasing text size in tables, using icons for main actions that users can remember from similar apps and web products, giving more prominence to search and filter results.

Playing around with concepts and visuals based on the rules we established for the main product to get some inspiration for the future. Here are some examples of material we did with Emilio García that was presented in Future Stack.
