Ability to remove border lines?

[winteriscariot]

i know i can change the color of the selector frame, but the actual lines around the tiles, can those be removed, or the colors changed?

[sagb]

no, change in code required.

Do you have any visibility problem with default border or just aesthetic issue?

[qsmodo]

I, for one, need the frame to see which window will be selected (I wonder what the OP has in mind with removing them), but I think it is too thick. It would be nice if the thickness could be adjustable.

[astier]

I also think that the frame is a little bit too thick. Would be nice if it would be possible to define the size of the frame.

I believe @qsmodo and @astier are referring to the thick, grey border that 'highlights' the currently-selected tile:

This colour can already be changed with -frame (though they're asking for an option to change the thickness of it).

Whereas I believe @winteriscariot is instead referring to the thin, white borders around all tiles:

The only way to change this is to set the -fg option, but that also changes the font colour.

It'd be nice if we could separately set the tile border and font colours. For example, I'd personally prefer that the tile borders were closer to the background colour (so as not to stand out so much), but that the font colour remained light/white.
