I can't find a way to change what the tag browse tree displays, but... We can hide things with css.
Whip out the style sheet, and try something like this:
.terminal-node:has(.tree-item:not([data-label="value"])) {
display: none;
}
This leaves behind a rather bad-looking branch thing. I'm trying to handle this gracefully, but...
The last item has a last-child css class, which makes the branchy thing different.
But I can't find this class anywhere :X
I tried grep -lri last-child on ignition's data folder and nothing came up.
edit:
You could remove the whole thing instead, I guess ?
.terminal-node .terminal-alignment:has(+ .tree-item[data-label="value"]) {
visibility: hidden;
}
