After all these years, I don't get why the InDesign team makes us work hard to do workarounds. It shouldn't matter if the team likes hanging bullets or not … it is often used in the field and InDesign should be made to work around the needs of designers and not force us to do workarounds for a simple feature that competitors had years ago.

to avoid ugly workarounds

How about a setting for WRAP INDENT? Then it would be much easier to set up multi-level lists, like manual indexes.

Negative margins (top/bottom) also very much required.

Please, I am missing this feature on a regularly basis. Negative indentation is so much used in web development…

Yes and yes. Frankly kind of ridiculous this still isn't an option.

I wholeheartedly support this although I actually came to uservoice today to post a different request that this feature would make redundant.

I had wanted to suggest that the left indent input box be positioned below the first line indent in all toolbar/UI environments as it bugs the **** out of me that when setting up bullets/lists you come to the Left Indent box first.

What's the issue with that, you might think?

Well you adjust it from 6.35mm to 5mm and then you get an error message stating that you've set an 'Invalid indent value. Indents cannot extend outside text frame.". To avoid this you need to skip the first box and go straight to the First Line Indent and set a minus value ex. -5mm. Now you can go back to the Left Indent and set that to 5mm either by taking your hand off the keyboard and using the mouse to click in the box or using the awkward Shift+TAB, to select the previous input box.

It would be so much easier for keyboard input to be able to use the TAB from the first to the next but you can't when setting the value lower that what it currently is (default 6.35mm) without hitting running into the stupid error message.

You wouldn't need to rearrange the UI if you'd allow for negative indents!!!

Oh my god yes

If you mean, negative indentation to overstep the left text frame margin to the left and the right text frame margin to the right, I'm totally in! Strongly seconded!!!
Negative Kerning to overstep the left frame border would be nice either!

Yes yes yes yes

This is an important feature. Although indenting everything ELSE is an ok work-around, it's a bit silly in such an advanced compositor environment.

This also might be a precursor to providing for real run-in headings. But I'm getting off-topic. I think there's an FR for that somewhere....

Would be more than great! Another benefit to this is that it would be much easier to split a paragraph, that now has to be indented, into more columns without the need of making adjustments to the par style!
