This content panel would be important in Draw and Impress, where the grid and guidelines are an important part of the design process for aligning objects and these settings may change from document to document and users shouldnt have to go into the Tools > Options dialog in order to modify them. The content panel will have checkboxes for the items in View > Grid and Helplines as well as View > Snap Lines. It will also contain the Tools > Options > LibreOffice Impress/Draw > Grid > Resolution's vertical and horizontal spinboxes and the Subdivision's horizontal and vertical spinboxes as a single spinbox. The result should look similar to what is available in Krita ( https://krita.org/wp-content/uploads/2016/03/gridsguidessnapping.png ) and the modification of the grid resolution and subdivision fields should be at the document level and not at the application level.
@Jay, I like the idea. I consider these functions to be "Layout" -- which would be a good name for the panel, or deck. But, does it need to be a full deck with its own tab bar button? Perhaps this content panel would fit well with the work to be done on a deck holding content panels of the "Page" tab--bug 83830
@Stuart, Impress is getting a 'Slide' content panel and Draw is getting a 'Page' content panel that will included in the Properties tab, when no object is being selected (bug 89466). This grid and guides content panel would be placed underneath them. It could also be included in the Page tab/deck in Writer, but the grid and guidelines arent widely used in it.
