Sorry I'm late, but I just listened to the Vim BOF session that Bram mentioned three months ago.
In the talk, Bram sounded quite evangelical with regard to promoting Vim usage, and he asked for suggestions on how he should best spend his limited time in working towards a new version ("Vim 8"). I am posting this introductory message with my response, plus a second message describing a feature I would like ("EncryptLine"). The best way to expand Vim usage IMHO would be to work out better default settings to improve the first hour of contact. In addition, perform necessary fixups, but resist new features. If I were starting Vim usage now, I would probably abandon it as soon as I discovered that pressing PageUp did NOT reverse the effect of PageDown. I still hate that! Vim has many wonderous features, but I imagine that many people don't stay to find them because of irritations like PgUp/PgDn. Highlighting all matches when searching is excellent, but there needs to be a way for a new user to turn it off. I map Space for this, however, it would be better to press Escape to clear highlights and message text (if Escape is pressed while in Normal mode, remove search highlights and clear any message). Maybe also have a way for this feature to be turned off. I won't say more now. If Bram feels that improved defaults would be worth investigating, a discussion here would probably be best. OTOH people who dream in Vim script may not be the best source of ideas on how Vim should be configured to win new converts. John
