I'm writing this blog to propose a small yet impactful feature that could significantly enhance the way many of us practice problems.

Feature Suggestion:

Make the "Problem Tags" section on problem pages collapsible by default, with an option to reveal them when desired.

Why this matters:

When practicing, many users (myself included) prefer solving problems without any hints. However, currently, the topic tags are visible right away, and even subconsciously, they can influence our thought process. This affects the learning experience and makes it harder to simulate a real contest environment where no hints are available.

On the other hand, if we disable tags entirely, we lose the ability to use them as a hint when we're stuck, which can be helpful to nudge our thinking in the right direction.

By hiding tags initially and allowing users to expand them when needed, we can:

• Think independently without any bias.
• Use tags later as a hint if we're stuck, helping guide our thoughts.
• Maintain a cleaner and more focused problem interface.

Proposed Behavior:

• The tags section should be collapsed by default during upsolving/practice.
• A small "Show Tags" button/link can be added to expand the section.
• Optionally, users could toggle this behavior in their settings.

This is a minor UI change, but it would greatly help users who want to challenge themselves and use tags only as a last resort. I believe many in the community would benefit from this addition.
