Add option in Tab Grease Pencil

Box deform on Ctrl+T

Example with lattice subdiv and spline deformations.

Box deform youtube demo

How to use: (same tutorial in addon preferences)
Use the shortcut Ctrl + T in available modes
The lattice box is generated facing your view so be sure to face canvas to avoid unintentional anamorphosis offset
Then use following shortcuts (also displayed in topbar):

Modes and deformation target:

• Object mode : The whole GP object is deformed
• GPencil Edit mode : Deform Selected points
• Gpencil Paint : Deform last Strokes

Shortcuts (also displayed in topbar):

• Spacebar / Enter : Confirm (Combine with Shift to let the lattice in place)
• Delete / Backspace / ctrl+T / Tab(twice) : Cancel
• M : Toggle Linear and Spline mode at any moment
• 1-9 top row number : Shortcut to subdivide box
• Ctrl + arrows-keys : Subdivide the box incrementally in individual X/Y axis

Notes :

If you return in box deform after applying with a ctrl+Z, you need to hit ctrl+T again to revive the modal.

A cancel warning will be displayed the first time you hit Tab (to avoid mis-canceling)

Multiframe edit selection works but you will only see the current frame during the modal

Rotate canvas

Customise shortcut in addons preferences, Default ctrl + alt + right-Click.
Shortcut changed are refreshed upon modifications.

Use Hud: Show angle value and lines.

Reset view (free navigation only): Click and release immediately without rotation to reset (up view point to world Z).

Incremental rotate Use Shift to increment rotation by a user-defined degree (in addon pref)

Save/restore camera rotation use button in sidebar

Viewport timeline scrubbing

Use Alt + Mid-Clic to call viewport timeline (customisable in addon prefs)

Use Ctrl to snap on keys

Options:

Always snap option snap on the keys

Rolling mode Discard timing information to jump quickly between keys

You have a lot more option to customise the Graphical aspect of the timeline.

Straight stroke

Straighten the stroke between first ans last point, keeping the points proportionally distant from each other.
You can affect influence in the redo panel (press F9 to pop up the redo panel).
Influence amount is remembered for next use (You can shift+click on the button to reset and force the use of 100% influence)

Import textured brush pack

Install included Grease pencil textured brush pack made by pepeland (Daniel Martinez Lara)
This is available in the sidebar > Tool > Brushes panel in the brush dropdown menu (where you can reset brush)
/!\ This will be removed once blender official asset manager will be active
