Matching 2 Images (Layers) With Selected Points |

I have 2 images (maps). One is a scale image from Google Maps. The other is an historic map that is not to scale. There are certain points of reference on each map that can be used to pull the historic map close to scale and provide reference to other points between the two maps. Is there a way to link 2 images with "points" on each and transform one of the two base on the those links?

I have an image that is from a picture of a drawing. It is all one layer. I would like to change certain specific colored pixels in specific areas from their current color to another. I know I can do this for the entire image.
In this case it is text and the current color is black which is present in other parts of the drawing and it is on a background color that is also in other parts of the drawing.
Something like a brush or eraser set so when it passes over an area would change just any black pixels to red might be best for this situation.
A rectangle or free select might work too, but in this case maybe a brush type thing seems like it would be easier.
It sort of sounds like the magic wand tool, but that is different and pretty unpredictable as well.

Histograms |

Hi
I am trying to use the histogram to carry out some editing of some of my photos. I select the histogram dialogue box from Windows / Dockable Dialogues and anchor it to my Dock where I want it or sometimes I will drag it and have it showing on the screen adjacent to the photo being edited. However, each time I select a slider to adjust e.g. Shadows and Hi lites the histogram shuts down (Disappears from the Dock or screen) hence I cannot see what adjustments are being made to the photo when I move a slider.
Any help appreciated please.

Just downloaded and installed GIMP2. I appear to have all the folders, sub folders etc but how does it open to a work screen similar to PSE or Luminar Neo which I already have.

Layer Group set active |

What is the syntax to set a layergroup (and possibly a layer within it) as active?
I have looked through the console and searched the web without success.
If, for instance, I wish to insert a layer it is straight forward - I can specify parent and position.
Should not the same syntax apply to other layer commands, or is it that the console has not been updated?
