I've tried a long time to find a way to make the tiny dots bigger or change color, that show empty spaces between characters.
Not sure if the size of empty space dots are controlled by the font selected. If so, there's little difference in dozens of Linux fonts, for size of spaces indicators - even if bold is selected. Generally, I use some mono bold font.
No idea if "spaces dots" color can be specified in a Geany color scheme, or if they're set to the same color as some other characters or...? Often I can't see some empty space dots unless I move close to the monitor. Those with perfect vision probably don't notice this.
Periods are often not big enough or enough contrast for scanning or editing code. Some fonts (e.g., mono on bold) may make periods or single quote / apostrophe a little bigger, but not much.
When I eliminate all fonts that don't put a slash or dot in zeroes, there aren't many left to find one with larger empty spaces dots or larger periods / commas, unless I choose a huge font size.
What "symbols" in the symbol list font selection does Geany preferences refer to? Thanks.
