+## ~~Easy Feature: Add Esc key close to Revise modal and add X to close in top right of modal in Dashboard and the Lookup LoRA Metadata from CivitAI, and omit lora triggerwords modals in the Builder UI.~~ COMPLETED
 
 ## Bug Fix: Batch Encoding Runs Before Job Skip/Continue/Resume check and will encode everything again even if it's already been completed. Also Continue/Resume Should NOT run by default if optional inputs are connected because changes to the optional inputs are not currently being tracked. We need to track connected node changes from each of the optional inputs, we could also use this step to save the workflow to the benchmark/session folder and compare the last run workflow to the current to track node changes and determine changes and also integrate currenly missing from optional inputs such as model, loras, prompts, etc.
 
 ## ~~Fix: Manifest doesn't need lora omit triggers list in every item~~ (DONE - already stripped in create_image_metadata via .pop())
 
-## Add attention options, xformers, sdpa, sage, flash, etc, option for test all, test all should clear ram & vram between each test.
+## ~~Add attention options, xformers, sdpa, sage, flash, etc, option for test all, test all should clear ram & vram between each test.~~ COMPLETED
+* **Status:** Added `attention_mode` config field supporting: default, xformers, pytorch, flash, sage, sage3, sub_quad, split. Use `"*"` to test all modes. Runtime switching via `transformer_options["optimized_attention_override"]` in ComfyUI's attention registry. Config Builder UI has dropdown+chips selector. Per-image metadata tracks which attention mode was used for dashboard filtering. Integrated into config expansion (Cartesian product with other params), skip/resume matching, and generation pipeline.
 
 # Deeper explained items to-do list
 
-#### **1. Skip Logic for Optional Inputs**
+#### **1. Skip Logic for Optional Inputs** COMPLETED
 
 * **Problem:** The `SamplerGridTester` node cannot reliably detect changes in optional inputs (`optional_model`, `optional_vae`, etc.) because standard `IS_CHANGED` logic relies on input hash comparisons, which don't update for passed objects in optional slots.
-
- Causes problems with:
-
- * Grid view using wrong model names
- * Job continuation/skipping/resuming
-
-
- * **Instruction:**
-1. **Modify `sampler_node.py`:** Implement the `IS_CHANGED` class method. Check if any optional input keys are present in the `kwargs`. If yes, return `float("NaN")` (standard ComfyUI trick to force execution) or a `uuid.uuid4().hex`.
-2. **Modify `generation_orchestrator.py`:** Update `check_if_job_completed`. If optional inputs were used, you cannot trust the `manifest.json` history for that specific job. Force a re-run or calculate a hash of the optional input's internal state (e.g., `model.model.diffusion_model`) if possible, otherwise force execution.
-
-
+* **Status:** Implemented `IS_CHANGED` classmethod in `sampler_node.py` that returns `float("NaN")` when any optional input is connected (forces re-execution), or a deterministic hash when no optional inputs are used (allows caching). Updated `check_if_job_completed` in `generation_orchestrator.py` to skip model/lora/prompt matching when optional inputs are connected, since those values come from upstream nodes whose changes can't be tracked. Added warning when resume mode is used with optional inputs.

 * **Problem:** Different models need different trigger words (e.g., "score_9, score_8" for Pony vs "masterpiece" for SD1.5).
-* **Instruction:**
-1. **Backend:** Add `model_specific_prompts` input to `SamplerGridTester` (dict or JSON).
-2. **Orchestrator:** In `generation_orchestrator.py`, inside the loop, check the current `conf["model"]`.
-3. **Injection:** Look up the model name in the map. If found, prepend/append the specific tags to `actual_positive_prompt` before encoding.
+* **Status:** Implemented as per-config `model_prompt_prefix` and `model_prompt_suffix` fields. These quality tags are prepended/appended to ALL prompts for a given config, wrapping around the entire prompt+triggers assembly. Added `_apply_model_prompt_affixes()` helper in `trigger_words.py`, integrated into both `build_prompt_with_triggers()` and `collect_unique_prompts_with_triggers()` for correct pre-encoding. Config Builder UI shows prefix/suffix text inputs in the Prompts section of each config. Fields persist through save/load and are passed through `expand_configs()` in `config_utils.py`.

-1. **Modify `config_utils.py`:** Update `expand_configs`.
-2. **Logic:** Detect brackets `[]` inside the LoRA string part. If found, treat it as a list.
-3. **Expansion:** Use `itertools.product` to generate separate config entries for each weight in the array (e.g., one config with 0.5, one with 0.8).
