Please bring back the old icon indicators! They were more than enough to figure out what's happening, no need for symbols. It made what looked like a clean sleek indicator into a tacky clipart decoration :(

just discoverd.. there is a simple (optical the old style) version: https://mods.factorio.com/mod/ixuBottleneck i'm fine with that

This is exactly what i need! Glad someone made it, this guy is a savior.

Just FYI the latest version has new icons which are visually a lot clearer.
Furthermore the linked version does not include the performance improvements introduced in version 0.11 and up.
Maybe give the new version a spin.

if you like 3D icone, i use it by default in my fork mod
