Currently, Gamma's responsive, block-based card system makes it impossible to adhere to strict corporate brand guidelines. While the fluid layout is excellent for quick content generation, enterprise users require absolute control over presentation aesthetics to match their company standards. The main problem we encounter is the inability to use free-form placement. We cannot place objects in arbitrary positions or overlap them, such as putting custom corporate vectors directly over images or text boxes. Furthermore, the AI dynamically adjusts layouts, meaning we cannot lock in a strict master slide template to ensure consistent background assets and proportions across all generated pages. To solve this, we propose adding a toggle for a Fixed-Canvas Mode alongside the current fluid layout. This mode would allow for absolute, pixel-perfect positioning of elements, object stacking with z-axis control, and the ability to define and lock unchangeable master slides. Implementing this feature would make Gamma a viable and powerful tool for corporate and enterprise teams who must strictly comply with established brand books and marketing layouts. Thank you for considering this enhancement for your roadmap.
