I wouldn't use semicolons in group titles. And I would probably go with singular "Report Layout". You can create a layout, open a layout, save a layout. All those actions apply to a single layout. We're not listing multiple layouts in that group:

• Report Layout
• Display Report Dialogs

The form caption is a little confusing. I see this screenshot early in the article... and I assume that you can only work with a Table Report in this example. I assume that's the app title. We need to make it clear that it's just a name of the currently loaded report. So maybe do it like this:

"TableReport.repx - Report Layout"

There's a strict limitation: app window is rather small and long captions don't fit. However, I'll do what I can to make it clear.

The application can load any report file, not just the one included.

I would set the context here, because I was a bit confused about the hamburger button, as I don't see it on the screenshot.

Suggested change

	1. Click the hamburger button, select the **Save** option, enter a report template name, and close the dialog.
	1. Once you're done with changes in the **Report Designer** dialog, click the hamburger button, select **Save**, and enter a report template name. Close the dialog.

BTW, it seems that I saved the report layout already, in this step. But then, in the next step, I have to click the Save button again (on the main app form). Should we explain why I need to go through the save process twice? Maybe we need to mention here, that this action doesn't actually save the report yet. But I'm not sure how it works.

[NickVolynkin]

Hmm. Maybe we should use completely distinct terms for file operations, such as Import from file and Export to file. This naming would highlight the difference from saving layouts in a Report Designer.

However, the methods to import and export layouts are still LoadFromFile and SaveToFile, as the Layout property inherits a simple TString.
