Thanks, text copy-pasting is an ancient missing feature.
Luckily, Allegro 5 already allows access to the operating system's copy buffer. I have an unpublished hack of Lix that hard-wires Ctrl+V to paste the copy buffer into the focused the Lix texttyping field.
On Linux, this already looks reasonable. Problem: On Windows, you also get an extra 'v' into the field. Example: Field held "abc", OS copy buffer contains "def", you press Ctrl+v, field now holds "abcdefv".
This feels too buggy to release, but it's a start.
Author field in editor should also prefill with your username. It doesn't. It's another bug.
Everybody: This kind of bug report is really valuable: Seemingly-obvious stuff that doesn't work as you expect, but that doesn't seem to bother anybody else. This is because long-term users learned to tolerate the flaw. Tolerating is a nasty solution. Please always complain about annoying stuff. Sometimes, there are low-hanging fruit that I overlooked, and that I can quickly fix with big impact.
