I am using vsvim and I think that it is a great tool.
The only issue I have is regarding changing/deleting text between braces and parentheses doesn't seem to work.
Here some examples I have verified in gvim, but do not seem to work in vsvim:
di(deletes the inner (...) block where the cursorda(deletes the inner (...) block where the cursor and removes the () characters tooci(changes the inner (...) block where the cursor is.ci{changes inside a {}ca{changes inside a {} and removes the {} characters too
I assume these are just features that have not been added.
Can someone confirm this?
                        
These issues are now fixed in VsVim 1.2. I tried all of your commands locally and they worked for me.
