Reverse or delete entire belt

[Xenophore]

TL;DR

I believe it would improve the user experience of the game if there were controls/actions on entire transport lines of belts: specifically, one to reverse them and one to mark them for deletion.

What ?

The recent FFF on a whole-belt reader https://factorio.com/blog/post/fff-405 offers the possibility of more whole-belt operations:

• There is no easy way to reverse the direction of an entire transport line. This propoal is for a control/key to reverse a belt segment (just as R rotates a segment) and an alt- or shift-key that performs the operation on a transport line (from end to end, or at least from splitter to sideloader)
• There could also be a control to extend the deconstruction of a belt to the whole transport line.

(Credit where due, the deletion has already been suggested here: viewtopic.php?f=38&t=112874&p=607886&hi ... lt#p607886. Apologies if I missed the reversal anywhere.)

Why ?

Reversal of a belt currently requires either rotating each segment or deconstructing and rebuilding (cut, reverse, paste) the belt, which is a slow and manual process, and prone to error in tight spaghetti. Deconstructing a belt in tight confines is also difficult and prone to collateral damage.

I know you're asking for vanilla, but here's a mod that does the reversing that you could use in the interim, and if it sees enough popularity could encourage the devs to add it:

The ability to reverse, delete, and upgrade whole sections of belt in Dyson Sphere Program is *really* convenient, and I'd love if Factorio had a similar capability.

A reasonable limitation would be to follow the belt forward and back, and stop when it hits a point of side loading or a splitter.

A reasonable limitation would be to follow the belt forward and back, and stop when it hits a point of side loading or a splitter.

The easy option (assuming that their code is anything like I think it is) would be to match the "wire whole belt" length.
