I think, it would be great to have a midi-eventlisteditor in Live. This editor is available in all other major sequencers. It's very useful to edit notes, controllers, bankselects, programchanges, sysex and so on in a numeric way.
The implementation should be easy for the abes
. Maybe a little button (near the foldbutton) to switch the midieditor from normal midiedit to listedit and back (of course). And, of course, some displayfilters 
A second little thing:
It should be possible to send mididata to the recorded channel. If a clip has midievents to more than 1 midichannel (can happen by importing a midifile format 0 or recording wiht a keyboardsplit), it should be possible to send the events to different (the original) channels. At the moment its not very logical, because i can record form all channels (see midiinputselect), but not send to all channels. The midiout-channelselector in the track should have something like "off" or "all" like the inputselector.
There should be a context-item like "split midiclip" too, to resolve such a clip to singelchannel tracks.
