Performance: 4-5 second delay with large notes (1500+ lines)

[way2pramil]

Description

KiNotes experiences a 4-5 second delay when opening/closing the plugin with large notes files (approximately 1500+ lines with embedded images).

Environment

• KiCad 9.0+
• Windows (reported on both mid-spec and high-spec PCs)
• KiNotes v1.5.1

Steps to Reproduce

1. Create or open a project with extensive notes (1500+ lines)
2. Include multiple embedded images in notes
3. Open/close KiNotes panel
4. Observe delay

Expected Behavior

Panel should open/close in <1 second regardless of note size.

Current Behavior

4-5 second delay on open/close with large notes.

Possible Causes (Investigation Needed)

• Markdown parsing overhead
• Image loading/rendering
• wxRichTextCtrl performance with large content
• File I/O blocking main thread

Priority

Low - Functional, but impacts UX with large projects

I'm seeing this issue with only the default notes added (ie no extra notes added)

Happening on 2 machines that are both running Ubuntu (One of 25.10 and the other 25.04)
