A client mod for Flackle with 48 plugins, themes and a live CSS editor.
Version 0.3.5, free and open source.
Before you install
Client mods are against Flackle's Terms of Service. Vackle runs inside your own app and never automates your account, but if losing it would be a disaster, don't use a client mod at all. Keep screenshots of Vackle out of servers that might ban you for it.
No. Vackle loads alongside Flackle and never edits its files. Your QuickCSS and themes are saved in Vackle's own data directory.
Run Vackle.exe again to uninstall. Everything returns to exactly how it was before.
