--- User plugins: cursor animation and snacks.nvim (picker + dashboard) customization

-- Confirm action for file-opening pickers: <CR> opens the selection as a
-- tab via `tabdrop` (:tab drop semantics — focus the buffer if it's already
-- visible in any tab, don't spawn a tab from an empty buffer, else open a
-- new tab). Explicit edit-cmd keybinds (<S-CR>/<c-v> vsplit, <c-s> split)
-- carry `action.cmd` and are passed through untouched.
local function tab_confirm(picker, item, action)
  local actions = require "snacks.picker.actions"
  if action.cmd then return actions.jump(picker, item, action) end
  return actions.jump(picker, item, vim.tbl_extend("force", {}, action, { cmd = "tabdrop" }))
end

-- Tab-on-enter + vsplit-on-shift-enter for the file-opening pickers only;
-- location pickers (lsp_*, lines, diagnostics, grep) and sources with their
-- own confirm (git_branches, projects) keep their defaults.

    },
  }
end

-- Smart picker: anchor to the current git repository. `config` runs when
-- the picker opens: cwd becomes the repo root (so the `files` finder scans
-- the whole repo, not just a rooter-chdir'd subdir) and `filter.cwd` drops
-- buffers/recent entries from other repos. Outside a repo, plain cwd
-- behavior is kept.
