Summary:
A feature where you can use utilize gems and create a "new day" of daily challenges.

In depth explanation:
Someone mentioned they have loads of gems and wished there was more they could do with them. Currently, gems are prioritized to be spent on premium lands, and after that the next best (generally) is to spend them on greenhouse/gazebo/keys from the in-game shop.
Other than that, gems serve no other purpose and aren't as rare as they probably should be.

My idea that I thought of, was to give players a chance to create a "new day" of daily challenges if a player finishes their daily challenges early that day. When I play the game, I play to finish the daily challenge and once completed, I typically stop feeding my addiction and don't play until new challenges are created the following day. If this feature was created, it would keep a player like myself, on longer playing.

*The reason I would want this feature is because currently for this album reset, I have completed the album already, and already have around 80 stickers out of 108 required. Unfortunately, I know there is no possible way to complete the sticker album twice in 50 days. If a feature like this existed where for x amount of gems you could get more daily challenges created, it would help complete the sticker album more than once in the 50 days. The reason I push so hard to finish the album each time is to get chest containing the decoration building. (The way it is designed currently, it would take an individual roughly 1-2 years in order to get each unique decoration from the sticker album rewards chest if that person finished the album every reset).

This suggestion is really only meant for players who are at high levels. I myself, am level 65 and am able to finish the daily challenges relatively easy, but I understand players that are lower levels struggle. I don't think finishing the sticker album is meant for lower level players.
