We use JIRA, and I have to take notes about my tickets in addition, especially for my dailies, but also throughout the day. I need this information readily available on my phone, and I need to be able to quickly move issues up and down in a sort of numbered list view, so I know what to do first.
I also need to be able to make links in the note, and (at least semi-)automatically include a link to the JIRA issue in the header/somewhere in the note. (Presumably with AppleScript from Safari.)
My first thought was Trello, but I do NOT like it, and AFAIK it has no scripting support natively, though there does seem to be workarounds. (And with Keyboard Maestro there are always workarounds of course).
I then tried Bear, which links easily, and is MUCH easier to use for linking, editing text and everything, but is REALLY fiddly to move things around with, especially on the phone.
TickTick is out due to both not letting me just move one issue up or down.
I am almost ready to go back to a pad and pencil, but I would REALLY think that one of the googleplex notes/list applications out there that support both Mac/Browser and Ios/mobile browser at least one would fit me.
