I would use this on every book or article project I do. It's incredible that it's not already an option in a paragraph style.

CRITICAL! This is pretty important. I do book design and many of the books are memoirs with tons of subheads scattered throughout the chapters, as well as "time breaks." In either case, I have to remember to apply a different para style to the next paragraph. This could be a great time saver! Great idea!

This is a significant issue. It can add dozens of styles to a project, and it wastes lots of time in proofing.

Yes! I probably google this once a year because I really can't believe it doesn't exist. We are talking about the most basic way to set most books (and other texts as well).

I'd really like to see an automated setup for this too.
Another way for Adobe programmers to consider could be to make the "Next style" function more advanced. If there was a way to refresh (reapply) all "next styles" the indent could be part of the Next styles of the header styles.
Today the Next style is only set when pressing enter at the end of the paragraph.

Along with the scripts suggested as temporary workarounds (waiting for Adobe) I recently noticed a way to deal with this using GREP search and replace: https://community.adobe.com/t5/indesign/remove-indent-in-first-line-find-change-command/td-p/4047487

I think it can a better choice for design. https://rankaroo.com/blog/

Yes, this is so needed in InDesign, it's so annoying having to have two different paragraph styles to fix this issue, Adobe, please do this. Just needs to have an option like... "Ignore indent after..." and then the ability to select the paragraph styles it does not apply to.

@grhafer30 — take a peek around for "Fixing paragraph style combinations" script, originally by Thomas Silkjær, but he hasn't done InDesign stuff in a long time, AFAIK, and many other people have produced their own hacked-to-their-own-purposes versions of the script.

I typeset a literary journal, and this one omission in InDesign means I have to create and manually apply two different styles that are differentiated only by paragraph indent.

I already have about 20 paragraph styles--for book reviews, poetry (you can imagine the variations with line breaks and forms), literary essays, etc.

This would be tremendously helpful. I go through book after book, checking first paragraphs that follow headings. Tremendous waste of time!

Please add this feature. And while you're at it, provide style support for run-in headings.

This would be most helpful

Yes please!

Yes, with Adam's ideas included. It should be variable, since designers often have odd ideas.

Please add my name to the list of those supporting what would be a very useful feature request. I particularly like Adam's language ("Set first line indent to _X_ when following:") as well. Thanks.

YES! Something that is so easy with CSS in web development... When you think of it, a lot of things in InDesign would improve if they would work more like CSS (cascading, selectors etc).

Would like that too. That may decreases paragraph styles a bit. Styles tends to be too numerous anyway.

Yes, that option would be useful.

I miss this option all the time. I did not miss it in the 10 year version of InDesign, because at this time I was still working with Calamus. But I find it frustrating to not have this option after 20 years.

It's a good idea and will cover 70% or 80% of cases, perhaps. But perhaps a little simplistic. Often the space before needs to be adjusted as well, and perhaps other style properties of the paragraph following a subhead. Anyway, it gets my vote as a step in the right direction!

Yes please!!! I hate having to make two paragraph styles just to not have indents on the beginning of a copy block.
