make cursor more visible
The cursor —a thin vertical bar — is virtually invisible. To check where it is, I have to enter a character!
It would be better to have a blinking underline or block (maybe white on red to indicate overwriting).
Is there an option to change the cursor appearance?
Width and Blink rate can be modified.
You might also want to turn on current-line highlighting. See Settings (menu) -> Preferences -> Editing -> Enable current-line highlighting.
Even if your caret was hard to see after Claudia’s suggestion (which it won’t be), this would help narrow down its location. :-)
