If not, does the default work for you? Dragging and dropping relies on Java so you may also want to make sure you are using the latest. mkowske wrote: 2) Pasting rich text into the notes field from another application (Thunderbird, Firefox, etc) produces gibberish. I have to turn on the option to paste everything as plain text which loses a lot of useful formatting. Have you tried the built-in Paste Special option in the Notes section? mkowske wrote: 3) No option to "hide" the program off to the side like it does on Windows. No transparent mode. Transparent Mode should exist as far as I know: View > Transparent Mode. The option to auto-hide is a Windows only feature. mkowske wrote: 4) No email integration. I've gathered that even if I did get drag and drop to work I still wouldn't be able to drag and drop a Thunderbird email. Dragging and dropping of email only works with Outlook on Windows. You may be able to drag an email to your desktop first and then into TheBrain on Linux. mkowske wrote: 5) Specifying programs to open an external file aren't remembered. This one seems more like a bug probably... e.g. I open .eml file from TheBrain, it asks for the program, I enter 'thunderbird', works great but I have to enter 'thunderbird' again next time I do this. This is simply how opening attachments works on Linux. mkowske wrote: 6) Trying to find a text expander that works .. AutoKey is what I have used in the past but when it is triggered in TheBrain it does some REALLY weird stuff. The text gets expanded to something unreadable and my keybaord keys no longer funciton how they are supposed to like they got remapped. I have to restart TheBrain to fix it. I am not sure what you are referring to here. Is this some 3rd party app that you're trying to get working with TheBrain?
