Easier suggestions in Intellij IDEA (no `CTRL+Space` and fuzzy search)

Question

I've installed IDEA today, on macOS and am wondering a couple of things to adapt usability to my needs:

• how to always show autocompletion automatically, as a sort of continuous suggestion, rather than having to always manually press ⌃Space?
• how to make the search among autocompletion fuzzier, without needing to type all the initial letters? Something like typing "fb" and it will match the variable foobar, rather than having to type "foob".

Answer 1

• Yes, this is achievable. Go to Settings -> Editor -> General -> Code Completion and check 'Show suggestions as you type'
• Partially achievable. You have to go again to Settings -> Editor -> General -> Code Completion and uncheck 'Match case'. This will help you with the completion but the results are not always as expected.
