some shortcomings of current notes app:
notes panel as it is now is a bit cripled. It should have same functionality as full-page editor (rich text, wysiwig, inline images) etc.
notes search should not only give you the list of notes in which the word is found, but also highlight the searched words in the notes text editor itself (both in panel as full-page)
button or shortcut to add current date/time-stamp (useful for manual logging and timekeeping)
possibility to zoom in/out of panels (like ctrl +/- functionality)
possibility to add multiple weblinks/bookmarks/screenshots to 1 note
integrating notes with tasks will be great, and offer a lot of synergies!
convert notes to tasks and vice versa
my favorite request: but not sure if it should be in notes or bookmarks or seperate:
https://forum.vivaldi.net/topic/54102/save-bookmarks-as-searchable-full-page:
"a kind of fullpage-bookmarks where also the page CONTENT is saved in a single file AND globally full-text searchable (see chrome extension https://github.com/gildas-lormeau/SingleFile, zotero.org, pocket.com). Can be used as an offline reading list, personal web-archive, research knowledgebase, etc. This would be a killer feature for sure!"
