I'm thinking making a second pair more looking like this.

[ericfennis]

I added two extra icons, but I don't know if the top ones are fitting the name separator? 🤔

[dgdavid]

Honestly, the top ones looks a bit weird as "separators". If you ask me, I'd say I prefer the last ones.

[ericfennis]

@dgdavid I totally agree.
the top ones look more like split-panes.

[ericfennis]

I removed the other two, so it is just those two.

[moeenio]

I'd call the removed ones split btw.

@ericfennis Is it just me or is the length of the line too long? Maybe either shorten it or increase the padding between the "brackets" and the line?

Idk just my thoughts.

[ericfennis]

@jletey I will try it, to shorten the line. For the brackets I tried, but it looked a bit weird. I think the 2px padding is fits the best.

[johnletey]

@ericfennis Sounds good, let me know what you come up with!

[ericfennis]

@jletey On the top are the one with shorter lines.

[ericfennis]

I implemented the top ones, thanks for the feedback!
