Coming from Vim? Onivim is actually Vim at the core, built on top of a fork of Vim called libvim.
However, there are several key aspects that are different or may be unexpected coming from Vim.
Onivim changes several default settings:
Tabs, Buffers, and Windows
In Vim, a 'tab' is a collection of windows. This is different from most 'modern' code editors - where a tab is a buffer in a split.
We made the trade-off of moving to the 'modern' definition: each window split in Onivim contains a list of buffers (editors), and thus, each UI 'tab' is really just a buffer.
However, we see value in the concept of the 'Vim-tab' - a grouping of window splits - and we want to keep that moving forward. We're working on adding a concept of workspaces, which encompass a grouping of window splits, as well some other properties (like the current working directory). Let us know if you have feedback on that concept by posting on that issue!
