While infuriating, a number of vim-latex's features can be customised without editing the source code.
call IMAP('EEA', 'EEA', 'tex')
EEA in insert mode will no longer insert the
F5 prompted environments
let g:Tex_PromptedEnvironments = 'equation,\[,align,align*'
eqnarray and some of the other discouraged/redundant environments from the
F5 prompt. Of course, you can add your own environments here as well.
There are also keybindings for
^F1 through to
let g:Tex_HotKeyMappings = 'bmatrix'
Again, you can customise this to suit your needs. (
bmatrix is one of vim-latex's defaults.)
