MathML Support
We need to have InDesign to support MathML, this is much awaited feature, but not supporting in InDesign yet.
Currently we're using 3rd party plugins such as MathType, MathTools, PowerMath, etc. but not meeting our expectation, also high license cost than InDesign.
@ALL: Please support to include this feature in InDesign in the very near release.

Yes, I too agree to bring this feature from FrameMaker to InDesign, will be more good to continue with InDesign

Viacheslav Horobchenko commented
Yes, from the very beginning of InDesign's history, I wish there was support for a set of scientific formulas. FrameMaker is very old now and completely inconvenient, in my opinion, not equal to InDesign. It would be interesting to combine their capabilities...

Raja, Gejaraj commented
Then, Adobe is promoting FrameMaker than InDesign? Definitely not, also FrameMaker not supporting MathML, but only the math expressions.
@Adobe: please respond

Viacheslav Horobchenko commented
If Adobe allows InDesign to work with fulloff math texts, then it will become a competitor for the Adobe Frame Maker application, so it is absolutely impossible...

Raja, Gejaraj commented
It's requested 6 years back, but no response / action from Adobe

Issue importing MsWord field code in Indesign

Julia Baker commented
I currently have to export images from MathType for use in InDesign. Onerous process.

Paula Vinagre commented
We need to make formulas in Indesign, equations, square root, etc.

We need math equation capabilities within InDesign ASAP.

@Adobe: not sure Adobe is serious about this request, since this is pending for a longtime, but much needed one. Due to this limitation, our clients/authors are started moving into another platform, such as TeX/LaTeX, which is actually free and rendering the math expressions in great manner.
If Adobe is still delaying, licenses count will be reduced much in the future. So please respond and comeback quickly with the updates.
Hope all the InDesign group supporters/users, will accept this.

For those who need math support within InDesign and are familiarized with Tex/Latex expressions, EasyMath Panel is available for download on adobe exchange: https://exchange.adobe.com/creativecloud.details.106188.easymathplus.html , https://exchange.adobe.com/creativecloud.details.105477.easymath.html .
Basically, this small piece of software helps you compose, previsualize, edit, insert, scale mathematical expressions and save them to disk as svg for later edits.

I agree with most of the comments. We need a mathematical tool within InDesign. Please add basic math equation functionality to InDesign.

Cameron Davidson commented
Yes, I agree, please add basic math equation functionality to InDesign. Perhaps accept Latex commands?

The number of Federal and State Government employees (including STEM workers) in the U.S. alone that are required to make all documents 508compliant should be enough to make it a priority to fix accessibility issues in your products. Please accommodate us, just as we have to accommodate our readers.

Please include a math equation tool in order for the users to be able to import math from word (editable) and to write from scratch (complicated) equations in indesign!

Baljit Dhaka commented
KIndly include features in InDesign to copy maths equations, charts, diagram etc of algebra, geometry, mensuration, pie charts, bar chart to copy from already typed in google live doc and MS word to directly paste in indesign. This is the most useful feature for publishing maths, reasoning books. Currently indesgin does not support this.
copy paste from google doc to InDesign mathematical equation features

I agree with most of the comments. We need a mathematical tool within InDesign. I teach economics at the university, and I miss this tool for my presentations. I hope that Adobe fix this problem as soon as possible. Best regards!

Vincent commented
Importing or placing the Word file with a lot of formules give huge problems. I hope Adobe will soon solve this problem!

Hello! Any updates on this request? It would be helpful if InDesign has this feature rather than get a third party plugin/extension.
