My happiest thing lately is to use NERDtree and then on selecting a bookmark, folder or file to then hit t to open that in a new tab.

So I have tabs and those are then split. Each subject of work or exploration has a tab with a few splits. I end up with much less clutter than sublime text. Easy to close out a tab.

Also ctrl-w v is my favorite way to split.
