Please allow the applications background and menu colour to be coordinated with the chosen colour theme instead of keeping the standard blue/grey background and main menu bar.

After using the new 'attachment feature' I immediately had the wish to show thumbnails for the images attached. :-)

Of course this would be nice for even more file types (eg. PDF and so on) - but I don't know how difficult this would be and I think images are the most useful case.

Maybe WIC would be helpful !?

WIC enables application developers to perform image processing operations on any image format through a single set of common APIs, without requiring prior knowledge of specific image formats.

I don't like rich text and don't use it anywhere, even in documents. Is there an option to disable it? For example, when I write numbered lists, the numbers are automatically "enriched". It breaks all my workflow because I need Asciidoctor/Markdown syntax for my lists. Also, it is very distracting.

Update:

As I discovered, this feature was _removed_ in 2.7.1 (CintaNotes 2.7: Options → Editor → Text formatting). I think it was a bad idea. A lot of technical-skilled people don't like Microsoft-Word-like ways to deal with text. Instead, lightweight markup languages like LaTeX, Asciidoctor, and Markdown are their best friends. I don't think we really _need_ Markdown in CintaNotes (although it would be great) - it could be too hard to add the parser/renderer and redesign the UI. But at least, please, give us back the option to use _simple plain text_, that is, to use Markdown or Asciidoctor _syntaxes_ (without the appropriate parsing and rendering).

Can we have a dark theme ?

Please

Add ability to specify secondary sort order.

For example now if notes are sorted by title, then notes having same title are sorted by creation date. Would be great to be able to sort them by text, for example.

It would be nice to be able to insert a horizontal rule (line) to separate sections in a note (much like the hr tag in html).

I suggest adding a hashtag recognition autotagging rule. Very often I happen to clip something that has a #hashtag in it, like #books or something like that, sometimes several hashtags like #geography #lakes # holidays. It is tedious to create an autotagging rule each time, so CintaNotes could recognize a hashtag and autotag it. This feature could be custom. Thank you. PS. For reference, this feature was implemented in Rednotebook Portable on portableapps.com.

Seamless transition between notes as they are solid text. So size of every note's preview matches its text length.
