In game there appear sometimes an error that you want to far from the city... but im really clicking inside of the town
A screenshot or a save game and a screenshot would helpful. Otherwise I have no clue what could happen.
It would be nice the price of buildings can me set to Low to extreme high
It's somehow possible... Basically all prices in the game can be adjusted via a GRF. BaseCosts
GRF is one of such. However, until it gets updated it won't be capable of handling house prices. Anyway, adjustable house prices is not a matter of this patch.
1) Show normal OTTD houses even if NewGRF is loaded. (Some NewGRF call on original graphics which arent shown in the housebuilder, UK Tai is an example)
UK Tai seems working all OK. Could you be more specific? Anyway, if original houses are turned off by some GRF, they are turned off. All you can do is to change the house set. Some GRFs have an option for keeping original houses.
2) Disable House Zoning. The 1-5 zone is a nice feature for controlling how the computer grows a city, but when placing houses manually it isnt intuitive as you cant see where the zones are. (EDIT: Its a wonderful patch, but i cant place any houses where i want them!!, stupid zoning).
For excessive town building there is scenario editor where the limit is turned off. In-game house placing is meant rather for sporadic building.
When it's about "seeing" the zones, you can move the cursor over town tiles and the zone will get highlighted (1 2 3 4 5 in the house picker window). Is the highlighting visible enough? Perhaps more contrast is needed... You can also ctrl+click while placing a house to open a dialog which will show the zone.
don't worry, be happy and checkout my patches
