When you make tables please please PLEASE can you make them so one can rearrange the columns and especially the rows by dragging (similar to Excel) or using a arrow shortcut. Also, don't make the cell padding etc to large so data is splayed out all over the place like in Evernote - its convenient to be to be able to to keep tables as small as poss. sometimes. Maybe being able to edit the table format (table padding, line width, colour, etc) would be cool.
If you include tables I will be migrating from EN. Looking at bear at the moment & looks cool.
Just to justify this a little further; I am basically split across Evernote & Excel at the moment using Excel for organising information into table format - much of which is just that, table format - info that requires a table in order to make sense of it, but does not require any formulas or macros. Thus I have to have heavy Excel open most of the time just for access to & review of my tables and cannot search through my note and table content in one search.
IMO, It would probably be best to make tables editable in a popup type window versus inline editing. Tables should be displayed well with nice formatting in a note, but not edited within the note.
I'd look at Table Flip @ https://tableflipapp.com/ for a good example of this. It syncs a markdown text editor (Marked 2) w/ the popup window app that allows real time editing of text tables in a more friendly spreadsheet type environment. I attached an image from the apps website to give you an idea of what this looks like.
