v22.1, Windows, 64bit

When I try to add text with a modified appearance to the library I get;

"Only basic appearances are supported for Text in Libraries. Advanced appearances have been dropped to add text to the current Library."

Or; "Couldn't save text asset having style. Remove the styles and try again”.

Seriously – no text styles in the library now? face palm

Ok, so 'Text library asset' is a thing now… whatever it’s supposed to be for, it’s braking basic library functionality.

If I want to add text with an advanced appearance to a library (ie. the ONLY sort of text I'd ever want to add to a library) then I have to add it with a non-text object. Then, I have to remove the useless group which gets added when taking things out of the library now, and delete the extra object. Time wasted...

The grammar mistakes show how much thought was put into this feature - please fix it or remove it.

Adobe says they made a purposeful change to Illustrator's Text Selection features. What do you think? Feature change or a unintended bug/change?

I suspect most users never use a forced line break, or know much about it.
So this illogical change in text selection to skip over selection just a line and jumps to a whole paragraph will never be seen. Doubt there was a user Feature request to change this also.

Illustrator 2018 changed how text is selected with triple clicks and using UP/Down Arrows.

A simple return/enter is a ^p, paragraph return.

A Shift-Return is a ^n, forced line break.
^n, ^p are commonly used to search for hidden formatting characters, like ^t for a tab.

One click is a Point, Two Clicks is a Word, Three clicks was Sentence.
Been that way since Illustrator 1.
Other programs have four and five click features to expand text selection from just a line to a paragraph or story. (inDesign/Quark/Word)

Now Three click, ignores forced line breaks, and selects text from Paragraph Return to Paragraph Return.

Note that Illustrator's search/replace feature only sees a forced line break, which is now ignored when selecting text. Just a hint that this change was not intentional to skip over a natural progression of selecting text.

Down Arrow text selection has changed also,

Just a down arrow goes to the same point in the line below.

Command Down arrow use to select text to the end of the line, ^p or ^n.
Now, Command Down ignores any ^n, forced line breaks and goes to the next ^p, paragraph return, not the end of the line.

Why the fuss?

Searching to replace tabs from long lists to change them to line breaks. Illustrator's Search/Replace function sees and has a short cut for a ^n Forced Line Break. It does not understand ^p as a Paragraph Return, nor has a shortcut to that formatting charter.

You Can "copy" the hidden paragraph return, and paste it in the field. It shows as a blank.

The integration of all products in the Adobe suite has helped my workflow tremendously with one exception. If I am working on a project requiring multiple outputs from Illustrator, Photoshop, Indesign, Animate, and Premiere, I have to create design templates for each (when possible) to get each program to use the fonts required for the project.
It would be nice if there were a tool allowing me to create a master style sheet for all outputs that would let me select the fonts used in ALL of my output files. Not only would this make my workflow more efficient, it could also allow me to change fonts globally which could provide the opportunity to show multiple design proposals.
