Merge duplicate posts
As an admin, I sometimes get the same request submitted multiple times. A merge feature that combines votes and redirects one post to the other would help keep things tidy.
Custom branding options
Let deployers customize the board name, accent color, and logo via environment variables. Right now it just says "Holler" — would be nice to show the actual project name.
Multi-language support (i18n)
All UI strings are hardcoded in English. A lightweight translation system using JSON files per locale would make Holler usable for non-English projects. Detect language from Accept-Language header.
Email notifications when status changes
If I leave my email when submitting feedback, I'd love to get notified when the status changes from "open" to "planned" or "done". A single email per change is enough.
Categories or tags for posts
A way to group feedback by topic (e.g., "UI", "API", "Documentation"). Could be a simple dropdown when submitting, and a filter on the main page.
Comments on posts
Allow users to discuss feedback items. Even just a flat list of replies per post would help — no need for threading. Keep it simple like the rest of the app.
Dark mode support
A dark theme option would be nice, especially for developers who browse at night. Could use a simple toggle that remembers the preference via cookie.
Add pagination to the posts list
Once there are more than ~30 posts, the page gets really long. Would be great to have a "Load more" button or page numbers. Should work with all existing filters and search.
