I've recently switched from Windows to Ubuntu and I don't miss anything except for one program named PhraseExpress. With it, you can create shortcuts for words, or fix spelling mistakes you make often, automatically.
- yuo → you
- rfg → Rindfleischverpackungsettikettierungsgerät
- ==> → $\Rightarrow$
and stuff like that. I haven't found a replacement for it on Linux, yet.
Would it be appropriate to ask for a program similar to that on Ask Ubuntu?
