What are your favorite add-ons/plug-ins/skills when using llama.cpp
I just finished setting up Qwen 3.5: 27B (Qwen3.6-27B-UD-Q4_K_XL.gguf) as my local model running on an old T7910 with dual xeon 2680 v4s 128gb of ram and a 3090.
The purpose of this VM was too handle all my automated and cron tasks instead of burning Anthropic Tokens and I have that all set up already. I still use my Cluade Pro subscription as my daily driver and for anytime I'm "building" something. But I have been messing around with Open Web UI and am pleasantly surprised at the speed and quality of Qwen 3.5:27B and may use it as my daily driver. (By daily driver I mean asking google-esq questions like "when should I fertilize my lawn", "who wrote the original blade runner book" "what's a good natural source of magnesium" ). I will still probably use Claude to build/code things.
But back to my main question. What are some bells and whistles I can use to Supe up the civic in my basement. I heard of things like searXNG, obsidian, n8n, Pi, etc but am pretty awful at deciphering between what's actually useful and what's a gimmick. What are some add-on people swear by and/or actually use effectively?
