In the next update, can the team/developer please add gradient option for both contact avatars and bubbles. please add option to increase/decrease the size of avatars separate from the text and so forth; as of right now, increasing the text also makes the avatars bigger. Add option to include avatars within the conversations as opposed to only having them in the conversation list. Lastly, add a color palette to the [app] theme section so we have additional options other than dark/light/black.
