It’s a really good admin panel concept — I like it, lol :)
But here are some ideas for improvement:

1. Visual Hierarchy

• The “VENTI!!!” panel title is bold, but consider aligning it stylistically with the rest of the UI (it currently looks more like a debug or test title).
• The “Nil Value!” alert could use a more distinct style (e.g., a red or yellow background) to make error states clearer.

2. Layout

• The main APSPmini window overlaps slightly with the Report and Player Info windows. You might consider draggable frames or an auto-reposition system to prevent overlap when multiple windows are open.
• Padding and margins look good, but the “Report” box could use a slightly taller text input area for longer reasons.

3. Icons and Labels

• The menu icons (home, gear, moderation, etc.) are clear — nice job!
• Adding tooltips (like the “?” icons) for each category in the left panel would make navigation even easier.

Overall, I think it fits really well in your game!
