I hear that, sometimes is it possible to have too much of a good thing? nah hehe
nCr, nPr, n^X worth of settlement stuff hehe.
-there were standalone cinderblock mods which had 17 different craftable cinderblock shapes,
-there was a 'scraphouse' standalone house mod, which had different kinds of plopable pallets. blue, yellow. pink, green and different kinds of wooden.
-plywood barriers and sandbags, i think DarthWayne or DDproductions have you covered on that.
you're going to love the scaffolding scrap-walks and bridges you can make with those,
as those also include the placeable plywood segments for windows.
I can't provide direct links to the first 2, as it appears those were taken down or hidden or something.
the same author as Pipes Galore also had some cement and concrete themed mods for a while too... they were awesome.
I hope that helps, and provides alternatives to the other existing options.
In the meantime, there will also be menu sorting mods in the pipeline, that will help you to sort mods as you like it,
I'm particularly looking forward to an xml version, that will let you really customize how those menus can cycle,
perhaps having different menu preferences per settlement,
allowing for customized 'thematic' building at each settlement you make, depending on how you envisage it.
this way, you won't be shown institute, enclave or prewar stuff anywhere but where you'd like it.
