| Drag & Drop in Layers Not Working |

For the longest time my drag and drop hasn't been working in the layers. When I grab the layer it moves across the screen as it should but for whatever reason when i drop it just doesn't move. I have been having to move layers around using the arrows at the bottom of the panel but I cannot use layer groups because I can't drop and drop layers into the group. I have tried resetting to default as well reinstalling GIMP.
Anyone else have this issue?

| Automate croping without reducing original image size |

Hello,
I don't do much image editing in anything resembling robust software. Apologies in advance if I use terms that are incorrect (please feel free to correct me).
What I'm trying to accomplish - I routinely digitize archived paper documents that are oftentimes spiral bound or comb bound. I usually unbind these to get good scans. The problem is, the scans always show the edges of the paper and the holes left from binding. I would like to automate 'whiting out' the margins to erase these marks on the scans so I can get a cleaner scan for archiving. I want to retain the original image size so the contents of the document look like the original, including keeping original margins and whatnot.
I am using GIMP 2.10. I found the BIMP plugin and started messing with the features in that. It seems like automated a crop is pretty straight-foward with that plugin, but I don't see a way to retain the original image size. GIMP has options to retain the original image size when cropping an image. Crop may not be the right function to accomplish what I want, so any advice is appreciated.

Hi there, thanks for reading this!
I have an image (layer) in b&w I want to use as a mask. In Photoshop, I used to make sure the layer is active and just press "strg+alt+2" or make a selection from the RBG or Green channel in one click. This gave me a selection that is hard in the bright white areas and softer in the areas where the light is less bright. I used this simple method to edit the highlights in my images with absolute precision, since I can paint on the b&w layer and exclude certain areas as well. It was so quick an easy and I was wondering if there is fast way to get the same selection out of gimp?
Thank you in advance

Further to Rich's post here:
https://www.gimp-forum.net/Thread-How-to...3#pid43283
I was finding the Filters -> Repeat and Filters -> Recently Used sometimes greyed out for the old script. So here's crosshair guides written for the v3 dialect of ScriptFu. It puts crosshair guides on the selected drawables.
Code:
#!/usr/bin/env gimp-script-fu-interpreter-3.0
(define (add-guides image drawable)
(let* ((drawable-width (gimp-drawable-get-width drawable))
(drawable-height (gimp-drawable-get-height drawable))
(offsets (gimp-drawable-get-offsets drawable))
(offset-x (car offsets))
(offset-y (cadr offsets))
(position-x (+ (/ drawable-width 2) offset-x))
(position-y (+ (/ drawable-height 2) offset-y)))
(gimp-image-add-vguide image position-x)
(gimp-image-add-hguide image position-y)))
(define (script-fu-crosshair-guides-v3 image drawables)
(script-fu-use-v3)
(gimp-image-undo-group-start image)
(do ((len (vector-length drawables))
(i 0 (+ i 1)))
((= i len))
; (gimp-message (string-append "i: " (number->string i)))
(add-guides image (vector-ref drawables i))
)
(gimp-image-undo-group-end image))
(script-fu-register-filter "script-fu-crosshair-guides-v3"
"Crosshair Guides v3"
"Place crosshair guides on all selected drawables."
"teapot"
"teapot"
"2025"
"*"
SF-ONE-OR-MORE-DRAWABLE
)
(script-fu-menu-register "script-fu-crosshair-guides-v3" "<Image>/Image/Guides")
