This small mod is basically an old Damage Preview mod (cursor text version) plus 2 most requested features:

Damage Type icons. If spell/attack has multiple damage components - all of them will be shown. As well as healing.
Concentration replacement warning. When you are concentrated on the spell, highlighting another spell which require concentration will include warning about replacement.

Plus a few damage preview bugs fixed, formatting improved, "0-0" values hidden etc.

Installation:
Manually drop pak file from archive to Mods folder (Appdata\Local\Larian Studios\Baldur's Gate 3\Mods) and enable it in in-game mod manager. Or use BG3MM/Vortex.

Uninstallation:
Disable/uninstall mod in in-game mod manager or in BG3MM/Vortex. Don't delete pak manually in Mods folder.
When uninstalling version installed via in-game mod manager from mod.io, unsubscribe on mod.io, otherwise in-game mod manager will try to install it on background again.

Compatibility:
Requires ImpUI.
KB/M and controllers UI compatible. Made to look great on any aspect ratio.
Should be compatible with any other mod that doesn't edit the same widget.
