Refactor and reorganize Builder "More" menu for better discoverability

[conorstrejcek]

Motivation

I've been using the Builder and noticed the "More" dropdown has become quite long, containing a mix of file operations, view settings, and grid tools. For long-time users, this is probably not an issue, but for newer users (like myself), it makes finding the right tool difficult.

Additionally, looking at Builder.tsx, the topBarChildren memoized value is currently handling all this logic in one place (roughly ~200 lines), which makes the component harder to maintain.

Proposed Changes

I’d like to work on a PR to reorganize this menu into logical groups and refactor the code to be more modular. However, since I am a new user/contributor, I want to make sure not to make any opinionated decisions on the organization. Here are my first thoughts, but I wanted to open a discussion for anyone who has opinions on this.

Suggested groupings

• File: New Puzzle, Import, Export
• Grid Tools: Clear Fill, Toggle Block/Bar/Rebus, Symmetry
• View/Settings: Mute, Keyboard toggle, Stats
• Account: Dashboard, Admin

In my personal UX opinion, I don't think we should necessarily hide these within nested navigation, and I think we could still have all of the options visible at once. My suggestion would be to put some small headers between each to make the groupings visually clear.

In addition, I'd like to extract each of the groups into smaller sub-components (e.g., <FileMenu />, <GridToolsMenu />) to reduce the overall cognitive load when editing the menu / Builder file.

I love the idea - thank you! I agree about avoiding nested nav if at all possible.

The only thing I'd like to be sure of with the reorg is that we test / confirm that performance remains acceptable. IIRC the reason for the giant memoized tree was that the whole menu was getting re-rendered on unrelated changes to the grid (i.e. navigating around when the menu wasn't even open). I'm sure there's a more sensible way to organize things that can still prevent those re-renders. So I say go for it!
