-# SpotNotes Future Implementation & Refactoring Plan
-## 1. Feature: Mobile UX & Responsive Overhaul
-- **Status:** **[To Do]**
-- **Action Plan:**
-  - **Audit & Consistency:** Review every application state (Login, Register, Admin Dashboard, Map View) to ensure visual parity with the desktop experience while optimizing for vertical screen constraints.
-  - **Compact Layout & Spacing:** Re-evaluate the spacing and layering of icons, buttons, and UI elements. Aim for a "small and tight" aesthetic that maximizes map visibility without cramping everything into an unreadable jumble.
-  - **Sidebar to Bottom-Sheet:** On mobile devices, explore transitioning the right-side drawer into a "Bottom-Sheet" component (sliding up from the bottom) to provide a more ergonomic, thumb-reachable interface for note lists.
-  - **Enhanced Touch Targets:** Standardize all interactive elements (buttons, icons, notepad list items) to a minimum 44x44px touch target to prevent accidental clicks and improve accessibility.
-  - **Responsive Modals:** Refactor modal windows to occupy 100% of the viewport height/width on small screens, ensuring that form inputs and the "Add Note" textarea remain fully visible above the virtual keyboard.
-  - **Mobile Navigation:** Consolidate the desktop navbar into a streamlined mobile header, utilizing a hamburger menu or action bar to keep the search functionality and account links accessible but unobtrusive.
