I just started using Spark and was about to request a new feature. I wanted to send the contents of a Clipboard (i.e. print screens, text snippets, etc…) and did not see a “Send Clipboard” button. I didn’'t want to go through the process of saving the Clipboard contents to a file and then use the “Send File” button. Anyway, I played around a little more and found the Ctrl-V was able to paste & send the Clipboard contents immediately as a file. This is probably documented somewhere, but I wanted to give this “undocumented” feature some kudos.
Thanks for the kudos. We did at one time have a “Send Clipboard” button in the chat window, but we are trying to minimize clutter and so removed it. Maybe I should make a list of “undocumented” features
