Editor preferences in IntelliJ (R)

I have used the R4IntelliJ plugin to edit R code in intellij and it works very well...but there are 3 technical detail that makes writing code cumbersome.

1. Failure to auto replace, say, { with {} -- that is automatically generate the corresponding bracket, brace, etc. 

2. Failure to automatically move the curser inside a { if the curser is currently located between a closed bracket and a curly brace, i.e.: 

)CURSER{          === Goal ===>         ) {CURSER}

3. if, say, this is true: {CURSER} pressing enter should be accompanied by a tab occurring automatically, i.e.,

if (1==1){

     print('hello world')

}

and not just:

if (1==1){

print('hello world')

}

I recognize some rewriting of R4IntelliJ is likely needed for some of these -- but is is possible to do any of these three just from the IntelliJ  settings?
