For whatever reason the lowercase and sentence case options are available from the top menu under Type, but are not enabled in the paragraph style options. Please cross-enable the features. I recently had a client change the ingredients in a 200 page recipe book from sentence case to all lowercase. I ultimately ran a find and replace by style using GREP code, but it would've been much easier and more efficient to be able to build this into the styles.

So far as I know, InDesign does not support style groups via xml import.

Why is this usefull?
If styles in a InDesign template organized into groups, we cannot refer with the attribute aid:pstyle and aid:cstyle to these styles and automatically apply these during xml import.

It would be nice to assign a paragraph style automatically depending on the “value” of a odd or even page? So you can for example make some styles have more margin at the right or left side, depending on odd or even.

Of course you can apply this with different paragraph style, but when a new page appears in the middle of a large document it would be very nice if this can go automatically.

I love using the shading for whole paragraph styles, but it would be nice to have shading for character styles as well. This would be nice for "highlighter" effects, which you just want to highlight a few lines or words. Just like applying an underline or strikethrough, but with a little more control over color, padding, maybe even shape?

Very often I use tables in multiple pages taht need to have the same dimensions. Being able to do that in Styles would be priceless.

The ability to create a TOC using a character style would save me a lot of time.

I would like to have external paragraph styles (and other styles too) so that they can apply to multiple documents and keep all documents using them in sync with the same set of styles.

A place to manage bulk style changes across paragraph, character, and object styles.

It's really confusing to have table and cell styles that only affect a subset of properties. Since I love using styles as a best practice, it never occurred to me that I was missing properties until running into numerous issues and doing a ton of research.
Examples of missing properties are header/footer rows for tables, and keep options for rows.

It would be really helpful when generating captions to be able to assign an object style in addition to a paragraph style. (Even better if there were multiple caption styles to choose from...)

It's great that Paragraph Borders are now included but it really needs an option to "Connect Border to Adjacent Paragraphs Sharing the Same Style" so that the border runs around multiple paragraphs if needed. I know you can work around this with forced line breaks and empty lines but that jars with me and doesn't give me proper style sheet control.

Stroke styles like those of Illustrator, where the library and styles can be created in either and shared between both programs

It would be nice if I could apply an object style to grouped objects. Especially useful when using only the position functions.

Allow us to create and name custom Stroke Styles. These would be in addition to Object Styles.

Stroke Styles could be used to specify a custom underline, strikethrough, or paragraph rule. Stroke Styles could also be applied to paths and called by Object Styles.

When placing a frame in the bleed area (-3mm), inDesign won't allow me to set the position of an image frame to -3mm, it has to be a positive value. Meaning I have to position image frames on the left-hand page manually, rendering the feature useless on the left hand page of each spread... If you can set the value to a negative amount in the regular coordinates palette why wouldn't this be mirrored in the styles?

When selecting more than one paragraph of text that therefore uses multiple paragraph styles, instead of saying (mixed) at the top of the styles palette, it would be really helpful if it could highlight which actual paragraph styles were in use. 'Multiple' is of no use - I can see there are multile styles just by looking at it!

We need to add conditional GREP formatting. For eg. in screen 1 (yellow highlighted text) tagged in xml, and are able capture with GREP styling. But when we put condition, it also captures unwanted text in same GREP style (cyan highlighted), tagged with same xml tag. It would be great as conditional text, i.e.. "IF x=y then DO 'this'" OTHERWISE APPLY 'this style'.

If such option available in indesign, it would be a great help as we are doing frontend xml publishing.

LOVE that borders and shading are now built into paragraph styles; but, I would like to be able to create a paragraph border with an inset (instead of an offset), or something like the "keep in frame" option for paragraph rules. The result is a paragraph outline in line with the other paragraphs above and below it, but with an inset paragraph inside the border.
