[Feature Request] Task List UI - wider name column & bulk actions

[rafstahelin]

Summary

Two UX improvements for managing tasks when running many exploration grids.

1. Wider Task Name Column

Task names are truncated early, making similar tasks hard to distinguish.

Current: style-lumen-id-karo-v8-promts-di...
Actual: style-lumen-id-karo-v8-promts-diverse

Suggestion:

• Double the task name column width, OR
• Make columns resizable by dragging

When running systematic parameter exploration, descriptive names help track iterations:

lumenA07V-g01-c3s4-1753
lumenA07V-g02-c3s4-1812  
lumenA07V-g03-c4s3-1830

These become indistinguishable when truncated.

2. Bulk Actions

Suggestions:

• Checkbox selection for multiple tasks
• "Select All" (respects current search filter)
• Bulk delete selected
• Bulk cancel selected (for queued tasks)

Use case: After a session with 20+ exploration grids, cleanup requires clicking delete on each task individually. With search filter + "Select All" + bulk delete, this becomes: filter → select all → delete.

Context

Using Lumi Batcher heavily for LoRA checkpoint × strength grid exploration. The API is excellent — these are minor UX polish items for high-volume usage.

Thank you for this great tool! 🙏
