P: Change the color or brightness of Grid Lines

Thank you Rick.

Thank you for taking the time to provide specifics about your issues with forum interaction. I appreciate that you did that. We will consider your comments as we review future procedures. 

Here is information for you that might help in the future if you decide again to request a
feature: https://community.adobe.com/t5/lightroom-classic-ideas/how-do-i-write-a-feature-request/idi-p/12386378 

Regarding your specific preference issue, which is unrelated to this thread, I recommend you make a post in a separate new Discussion thread to help obtain steps on how to correct your issue. Please provide complete information so that others may help you quickly and completely.  If it were a known issue, I would direct you to the authoritative post, however it is not.

OK. I put up a post with two items in it. (1) I'm told it's the wrong place to post this. (2) I'm told I can only put one idea in one post. (3) I'm told it should be merged with another thread that doesn't really deal precisely with what I raised. A normal company really interested in customer feedback and ideas would instead return a message that says: "Thank you for your suggestions. We will forward them to the appropriate people for consideration and let you know the outcome." Instead I'm treaated to a pile of proedural crap. Do you understand now? And to boot, here's another one: only the first two tabs of Lightroom Preferences have anything on them - the rest are blank. Way to go Adobe + Apple. And no, I'm not posting this anywhere else. Someone should just tell me whether it's a known issue and what to do about it. There's enough money in Adobe (I've been examining the Corporate 10-K) to put some serious resources into customer care - for a change, and take this albatross of a "Community" off our backs.

"The only thing I'm interested in is that recommendations I put forward regardless of where or how written get communicated to the people who matter"

And if rearranging the chairs is exactly what is needed to do that?

Again, if you could say specifically to what you are taking exception, we might be able address that - or at least explain it. 

The only thing I'm interested in is that recommendations I put forward regardless of where or how written get communicated to the people who matter. To whoever manages this community, doing that would be much more appreciated than re-arranging the deck chairs on the Titanic.

@MarkDS  I am not sure to what you are referring. Can you be more specific?

Edits to posts, moves between forums, including merging threads, are designed to give your post the maximum impact and visibility with our Product Management and Development teams. 

When forum posting guidelines are more important than the substance of the ideas being communicated, something has gone terribly wrong. I seldom come to this Community for that very reason, but thought I would try again. Alas I have failed again, because form continues to be more important than substance here. Well, so be it, life's too short - there are alternatives.

The "Custom Package" interface has a blue-lined grid to assist with photo placement. The problem is that the gridlines are far too weak, causing eye strain. This is a long-standing problem, but now aggravated with our higher resolution monitors. I would appreciate if the grid lines could be made more pronounced/visible. Also, I would like to see Adobe introduce functionality of the keyboard arrow keys for accurately guiding photos into their precise intended locations in the grid.

So, no fix for this yet?  WTH?

I don't know why this issue is flagged as "Answered" as for most it is not. For some turning off/on the GPU helps but for a lot it does not. Myself included. The grid in the crop module is so faint that at first I thought it had gone. Changing the GPU setting had no effect.
