[bug] "export settings" doesn't export custom marker settings - separate export button plzze?

[piecevcake]

Describe the bug
click "export & import" "export local data" doesn't save

To Reproduce
click "export & import" "export local data" in a profile that has custom marker settings/colours
"import local data" in another profile

Expected behavior
Import data should overwrite the custom marker settings

Screenshots

Which OS, Firefox edition, Textmarker version
W10, FF all, Textmarker all (I have tried and failed to export settings for years)

Additional context
Please add separate button to export settings?
Thank you!
