UI: terminal tabs

[christianparpart]

Provide terminal tabs.

Depends on #956

This requires basic support for the tree structure windowing.

• per output window, only one session is being displayed (no session management in this ticket yet).
• one session can contain multiple tabs (by default being displayed in the bottom line)
• one tab can contain multiple panes (tree structured)
• one pane contains exactly one single terminal view

Contour: Actions

• NewTab (Ctrl+Shift+T)
• SelectNextTab (Ctrl+Shift+PgDn)
• SelectPrevTab (Ctrl+Shift+PgUp)
• SelectTab(index) (Ctrl+Alt+)
• CloseTab (Ctrl+Shift, C)

TODO Items

• TerminalTree: terminal tree data structure (session/panel/pane)
• action: rename session (default: indexed)
• replace single-TerminalView with TerminalTree
• action: rename panel (default: indexed)
• action: rename pane (default: terminal title)
• action bindings

CloseTab (Ctrl+Shift, C)

On Linux it'd be a conflicting habit with some of the existing terminals that use this to Copy.
Also, from my own experience I'd suggest implementing MRU tab switching, it's certainly a "killer" feature that iTerm has and lots of terminals lack of.

[christianparpart]

These where initial shortcut ideas m but yes, that will ask be certainly configurable as usual.

Many thanks on the iTerm tip @poige , also. :-)

Any updates on this?

PS: I also interested in feature to split terminal window like Tilix does

Yes, I saw #91 but there's been no change since the creation of these two

Hey @denisgolius. Many thanks for your continued interest in Contour :)

This is still pretty high on the list. We're currently about to release 0.4.0, which contains the major frontend refactor, which is considered a prerequisite for also this ticket here.

As soon as we've release 0.4.0 (which requires #1228 to be fixed), I can start working on tabs and then splits. :)

Why not basic tab support in one release, and more complex pane and tree structures in a later release? Having even basic tabbing support would be a huge step up for user friendliness.

[christianparpart]

Good morning. This is a good idea. We will however first release 0.4.0 ASAP, and then care about Tabs. Splits need more thought, but can be easily deferred, you are right. :)
